LP2985-N SNVS018Y–MARCH2000–REVISEDDECEMBER2016 www.ti.com 7 Detailed Description 7.1 Overview The LP2985-N family of fixed-output, ultra-low-dropout and low-noise regulators offers exceptional, cost-effective performance for battery-powered applications. Available in output voltages from 2.5 V to 5 V, the family has an output tolerance of 1% for the A version (1.5% for the non-A version) and is capable of delivering 150-mA continuous load current. Standard regulator features, such as overcurrent and overtemperature protection, are alsoincluded. Using an optimized vertically integrated PNP (VIP) process, the LP2985-N contains several features to facilitate batterypowereddesigns: • Multiplevoltageoptions • Lowdropoutvoltage,typicaldropoutof300mVat150-mAloadcurrentand7mVat1-mAload. • Lowquiescentcurrentandlowgroundcurrent,typically850-μAat150mAload,and75-μAat1-mAload. • A shutdown feature is available, allowing the regulator to consume only 0.01-µA typically when the ON/OFF pinispulledlow. • Overtemperature protection and overcurrent protection circuitry is designed to safeguard the device during unexpectedconditions • Enhanced stability: The LP2985-N is stable with output capacitor ESR as low as 5 mΩ, which allows the use ofceramiccapacitorsontheoutput. • Low noise: A BYPASS pin allows for low-noise operation, with a typical output noise of 30 µV , with the RMS useofa10-nFbypasscapacitor. 7.2 Functional Block Diagram 7.3 Feature Description 7.3.1 MultipleVoltageOptions In order to meet different application’s requirement, the LP2985-N family provide multiple fixed output options from2.5Vto6.1V.Consultfactoryforcustomvoltages. 7.3.2 OutputVoltageAccuracy Output voltage accuracy specifies minimum and maximum output voltage error, relative to the expected nominal output voltage stated as a percent. This accuracy error includes the errors introduced by the internal reference and the load and line regulation across the full range of rated load and line operating conditions over temperature, unless otherwise specified by the Electrical Characteristics. Output voltage accuracy also accounts forallvariationsbetweenmanufacturinglots. 12 SubmitDocumentationFeedback Copyright©2000–2016,TexasInstrumentsIncorporated ProductFolderLinks:LP2985-N

LP2985-N www.ti.com SNVS018Y–MARCH2000–REVISEDDECEMBER2016 Feature Description (continued) 7.3.3 Ultra-Low-DropoutVoltage Generally speaking, the dropout voltage often refers to the voltage difference between the input and output voltage (V = V – V ), where the main current pass-FET is fully on in the ohmic region of operation and is DO IN OUT characterized by the classic R of the FET. V indirectly specifies a minimum input voltage above the DS(ON) DO nominal programmed output voltage at which the output voltage is expected to remain within its accuracy boundary. If the input falls below this V limit (V < V + V ), then the output voltage decreases in order to DO IN OUT DO followtheinputvoltage. 7.3.4 LowGroundCurrent LP2985-N uses a vertical PNP process which allows for quiescent currents that are considerably lower than thoseassociatedwithtraditionallateralPNPregulators,typically850 μAat150-mAloadand75 μAat1-mAload. 7.3.5 SleepMode When pull ON/OFF pin to low level, LP2985-N enters sleep mode, and less than 2-μA quiescent current is consumed. This function is designed for the application which needs a sleep mode to effectively enhance battery lifecycle. 7.3.6 InternalProtectionCircuitry 7.3.6.1 ShortCircuitProtection(CurrentLimit) TheinternalcurrentlimitcircuitisusedtoprotecttheLDOagainsthigh-loadcurrentfaultsorshortingevents.The LDO is not designed to operate in a steady-state current limit. During a current-limit event, the LDO sources constant current. Therefore, the output voltage falls when load impedance decreases. Note also that if a current limit occurs and the resulting output voltage is low, excessive power may be dissipated across the LDO, resulting inathermalshutdownoftheoutput. A foldback feature limits the short-circuit current to protect the regulator from damage under all load conditions. If V is forced below 0 V before EN goes high and the load current required exceeds the foldback current limit, OUT thedevicemaynotstartupcorrectly. 7.3.6.2 ThermalProtection The LP2985-N contains a thermal shutdown protection circuit to turn off the output current when excessive heat is dissipated in the LDO. The thermal time-constant of the semiconductor die is fairly short, and thus the output cyclesonandoffatahighratewhenthermalshutdownisreacheduntilthepowerdissipationisreduced. The internal protection circuitry of the LP2985-N is designed to protect against thermal overload conditions. The circuitry is not intended to replace proper heat sinking. Continuously running the device into thermal shutdown degradesitsreliability. 7.3.7 EnhancedStability The LP2985-N is designed specifically to work with ceramic output capacitors, utilizing circuitry which allows the regulator to be stable across the entire range of output current with an output capacitor whose ESR is as low as 5mΩ.Foroutputcapacitorrequirement,pleaserefertoOutputCapacitor. 7.3.8 LowNoise The LP2985-N includes a low-noise reference ensuring minimal noise during operation because the internal reference is normally the dominant term in noise analysis. Further noise reduction can be achieved by adding an externalbypassbapacitorbetweentheBYPASSpinandtheGNDpin.

LP2985-N www.ti.com SNVS018Y–MARCH2000–REVISEDDECEMBER2016 8 Application and Implementation NOTE Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 8.1 Application Information The LP2985-N is a linear voltage regulator operating from 2.5 V to 16 V on the input and regulates voltages between 2.5 V to 6.1 V with 1% accuracy and 150-mA maximum output current. Efficiency is defined by the ratio of output voltage to input voltage because the LP2985-N is a linear voltage regulator. To achieve high efficiency, the dropout voltage (V – V ) must be as small as possible, thus requiring a very-low-dropout LDO. IN OUT Successfully implementing an LDO in an application depends on the application requirements. If the requirements are simply input voltage and output voltage, compliance specifications (such as internal power dissipation or stability) must be verified to ensure a solid design. If timing, start-up, noise, power supply rejection ratio(PSRR),oranyothertransientspecificationis required,thenthedesignbecomesmorechallenging. 8.2 Typical Application *ON/OFFinputmustbeactivelyterminated.TietoV ifthisfunctionisnottobeused.

The efficiency of the LP2985-NinthisconfigurationisV /V =76.7%.Toachievethesmallestformfactor,theSOT-23packageis OUT IN selected. Input and output capacitors are selected in accordance with the Capacitor Characteristics section. Ceramic capacitances of 1 μF for the input and one 2.2-μF capacitor for the output are selected. With an efficiency of 76.7% and a 150-mA maximum load, the internal power dissipation is 150 mW, which corresponds to a 26°C junction temperature rise for the SOT-23 package. With an 85°C maximum ambient temperature, the junction temperatureisat111°C.Tominimizenoise,abypasscapacitance(C )of0.01 μFisselected. BYPASS 8.2.2.1 ExternalCapacitors Like any low-dropout regulator, the LP2985-N requires external capacitors for regulator stability. These capacitorsmustbecorrectlyselectedforgoodperformance. 8.2.2.1.1 InputCapacitor An input capacitor whose capacitance is ≥ 1 µF is required between the LP2985-N input and ground (the amount ofcapacitancemaybeincreasedwithoutlimit). This capacitor must be located a distance of not more than 1 cm from the input pin and returned to a clean analogground.Anygoodqualityceramic,tantalum,orfilmcapacitormaybeusedattheinput. NOTE Tantalum capacitors can suffer catastrophic failure due to surge current when connected to a low-impedance source of power (like a battery or very large capacitor). If a Tantalum capacitor is used at the input, it must be ensured by the manufacturer to have a surge currentratingsufficientfortheapplication. There are no requirements for ESR on the input capacitor, but tolerance and temperature coefficient must be considered when selecting the capacitor to ensure the capacitance will be ≥ 1 µF over the entire operating temperaturerange. 8.2.2.1.2 OutputCapacitor The LP2985-N is designed specifically to work with ceramic output capacitors, utilizing circuitry which allows the regulator to be stable across the entire range of output current with an output capacitor whose ESR is as low as 5 mΩ. It may also be possible to use tantalum or film capacitors at the output, but these are not as attractive for reasonsofsizeandcost(seeCapacitorCharacteristics). The output capacitor must meet the requirement for minimum amount of capacitance and also have an ESR value which is within the stable range. Curves are provided which show the stable ESR range as a function of loadcurrent(seeFigure22). Figure22.

LP2985-N www.ti.com SNVS018Y–MARCH2000–REVISEDDECEMBER2016 NOTE The output capacitor must maintain its ESR within the stable region over the full operating temperaturerangeoftheapplicationtoassurestability. TheLP2985-Nrequiresaminimumof2.2 µFontheoutput(outputcapacitorsizecanbeincreasedwithoutlimit). It is important to remember that capacitor tolerance and variation with temperature must be taken into consideration when selecting an output capacitor so that the minimum required amount of output capacitance is provided over the full operating temperature range. Ceramic capacitors can exhibit large changes in capacitance with temperature (see Capacitor Characteristics). The output capacitor must be located not more than 1 cm from theoutputpinandreturnedtoacleananalogground. 8.2.2.1.3 NoiseBypassCapacitor Connecting a 10-nF capacitor to the BYPASS pin significantly reduces noise on the regulator output. The capacitorisconnecteddirectlytoahigh-impedancecircuitinthebandgapreference. Because this circuit has only a few microamperes flowing in it, any significant loading on this node will cause a change in the regulated output voltage. For this reason, DC leakage current through the noise bypass capacitor mustneverexceed100nAandmustbekeptaslowaspossibleforbestoutputvoltageaccuracy. The types of capacitors best suited for the noise bypass capacitor are ceramic and film. High-quality ceramic capacitors with either NPO or COG dielectric typically have very low leakage. 10-nF polypropolene and polycarbonate film capacitors are available in small surface-mount packages and typically have extremely low leakagecurrent. 8.2.2.2 CapacitorCharacteristics The LP2985-N was designed to work with ceramic capacitors on the output to take advantage of the benefits they offer: for capacitance values in the 2.2-µF to 4.7-µF range, ceramics are the least expensive and also have the lowest ESR values (which makes them best for eliminating high-frequency noise). The ESR of a typical 2.2- µF ceramic capacitor is in the range of 10 mΩ to 20 mΩ, which easily meets the ESR limits required for stability bytheLP2985-N. One disadvantage of ceramic capacitors is that their capacitance can vary with temperature. Most large value ceramic capacitors (≥ 2.2 µF) are manufactured with the Z5U or Y5V temperature characteristic, which results in thecapacitancedroppingbymorethan50%asthetemperaturegoesfrom25°Cto85°C. This could cause problems if a 2.2-µF capacitor were used on the output because it will drop down to approximately 1 µF at high ambient temperatures (which could cause the LM2985 to oscillate). If Z5U or Y5V capacitorsareusedontheoutput,aminimumcapacitancevalueof4.7 µFmustbeobserved. A better choice for temperature coefficient in ceramic capacitors is X7R, which holds the capacitance within ±15%.Unfortunately,thelargervaluesofcapacitancearenotofferedbyallmanufacturersintheX7Rdielectric. Tantalum capacitors are less desirable than ceramics for use as output capacitors because they are more expensivewhencomparingequivalentcapacitanceandvoltageratingsinthe1 µFto4.7 µFrange. Another important consideration is that tantalum capacitors have higher ESR values than equivalent size ceramics. This means that while it may be possible to find a Tantalum capacitor with an ESR value within the stable range, it would have to be larger in capacitance (which means bigger and more costly) than a ceramic capacitorwiththesameESRvalue. Note that the ESR of a typical tantalum will increase about 2:1 as the temperature goes from 25°C down to −40°C,sosomeguardbandmustbeallowed. 8.2.2.3 ON/OFF InputOperation TheLP2985-NisshutoffbydrivingtheON/OFFinputlow,andturnedonbypullingithigh.Ifthisfeatureisnotto beused,theON/OFF inputmustbetiedtoV tokeeptheregulatoroutputonatalltimes.

LP2985-N SNVS018Y–MARCH2000–REVISEDDECEMBER2016 www.ti.com To assure proper operation, the signal source used to drive the ON/OFF input must be able to swing above and below the specified turn-on/turn-off voltage thresholds listed in the Electrical Characteristics section under V . To prevent mis-operation, the turn-on (and turn-off) voltage signals applied to the ON/OFF input must ON/OFF haveaslewratewhichis≥ 40mV/µs.

ON/OFF 8.2.2.4 ReverseInput-OutputVoltage The PNP power transistor used as the pass element in the LP2985-N has an inherent diode connected between the regulator output and input.

ReverseCurrentProtection However, if the output voltage is higher than the input voltage, this diode turns ON, and current flows into the regulator OUT pin.

LP2985-N www.ti.com SNVS018Y–MARCH2000–REVISEDDECEMBER2016 Power dissipation can be minimized, and greater efficiency can be achieved, by using the lowest available voltage drop option that would still be greater than the dropout voltage (V ). However, keep in mind that higher DO voltagedropsresultinbetterdynamic(thatis,PSRRandtransient)performance. On the SOT-23 (DBV) package, the primary conduction path for heat is through the device leads to the PCB, predominately device lead 2 (GND). TI recommends that the trace from lead 2 be extended under the package bodyandconnectedtoaninternalgroundplanewiththermalvias. The maximum allowable junction temperature (T ) determines maximum power dissipation allowed (P ) J(MAX) D(MAX) forthedevicepackage. Power dissipation and junction temperature are most often related by the junction-to-ambient thermal resistance (R ) of the combined PCB and device package and the temperature of the ambient air (T ), according to θJA A Equation2orEquation3: T =T +(R ×P ) (2) J(MAX) A(MAX) θJA D(MAX) P =(T -T )/R (3) D(MAX) J(MAX) A(MAX) θJA Unfortunately, this R is highly dependent on the heat-spreading capability of the particular PCB design, and θJA therefore varies according to the total copper area, copper weight, and location of the planes. The R recorded θJA in Thermal Information is determined by the specific EIA/JEDEC JESD51-7 standard for PCB and copper- spreading area, and is to be used only as a relative measure of package thermal performance. For a well- designed thermal layout, R is actually the sum of the package junction-to-case (bottom) thermal resistance θJA (R )plusthethermalresistancecontributionbythePCBcopperareaactingasaheatsink. θJCbot 8.2.2.6 EstimatingJunctionTemperature The EIA/JEDEC standard recommends the use of psi (Ψ) thermal characteristics to estimate the junction temperatures of surface mount devices on a typical PCB board application. These characteristics are not true thermal resistance values, but rather package specific thermal characteristics that offer practical and relative means of estimating junction temperatures. These psi metrics are determined to be significantly independent of copper-spreading area.

Place ground return connections to the input and output capacitor, and to the LDO ground pin as close as possible to each other, connected by a wide, component-side, copper surface. The use of vias and long traces to create LDO circuit connections is strongly discouraged and negatively affects system performance. This grounding and layout scheme minimizes inductive parasitics, and therebyreducesload-currenttransients,minimizesnoise,andincreasescircuitstability. A ground reference plane is also recommended and is either embedded in the PCB itself or located on the bottom side of the PCB opposite the components. This reference plane serves to assure accuracy of the output voltage, shield noise, and behaves similar to a thermal plane to spread (or sink) heat from the LDO device. In mostapplications,thisgroundplaneisnecessarytomeetthermalrequirements. 10.2 Layout Example VIN VOUT Input IN OUT Output Capacitor Capacitor GND Ground Bypass Capacitor ON/OFF BYPASS Figure39.
