LP2980-N www.ti.com SNOS733P–APRIL2000–REVISEDSEPTEMBER2016 7 Detailed Description 7.1 Overview The LP2980-N is a 50-mA, fixed-output voltage regulator designed specifically to meet the requirements of battery-powered applications. Available in output voltages from 2.5 V to 5 V, the device has an initial output voltage tolerance of ±0.5% for the A grade (1% for the non-A version). Using an optimized vertically integrated PNP(VIP)process,theLP2980-Ncontainsthesefeaturestofacilitatebattery-powereddesigns: • Fixed5-V,4.7-V,3.3-V,3-V,and2.5-Voutputversions • Low-dropoutvoltage,typicaldropoutof120mVat50-mAloadcurrentand7mVat1-mAload • Lowgroundcurrent,typically370 μAat50-mAloadand80 μAat1-mAload • A sleep mode feature is available, allowing the regulator to consume less than 1 µA typically when the ON/OFF pinispulledtolessthan0.18V. • Overtemperature protection and overcurrent protection circuitry is designed to safeguard the device during unexpectedconditions. 7.2 Functional Block Diagram 7.3 Feature Description 7.3.1 MultipleVoltageOptions To meet the different application requirements, the LP2980-N provides multiple fixed output options from 2.5 V to 5V. 7.3.2 High-AccuracyOutputVoltage With special careful design to minimize all contributions to the output voltage error, the LP2980-N distinguishes itself as a very high-accuracy output voltage micropower LDO. This includes a tight initial tolerance (0.5% typical), extremely good line regulation (0.007%/V typical), and a very low output voltage temperature coefficient, makingthepartanideallow-powervoltagereference. 7.3.3 Ultra-Low-DropoutVoltage Generally speaking, the dropout voltage often refers to the voltage difference between the input and output voltage (VDO = V – V ), where the main current pass-FET is fully on in the ohmic region of operation and is IN OUT characterized by the classic R of the FET. VDO indirectly specifies a minimum input voltage above the DS(ON) nominal programmed output voltage at which the output voltage is expected to remain within its accuracy boundary.

LP2980-N SNOS733P–APRIL2000–REVISEDSEPTEMBER2016 www.ti.com Feature Description (continued) 7.3.4 LowGroundCurrent LP2980-N uses a vertical PNP process which allows for quiescent currents that are considerably lower than thoseassociatedwithtraditionallateralPNPregulators,typically370 μAat150-mAloadand80 μAat1-mAload. 7.3.5 SleepMode When pulling the ON/OFF pin to low level, LP2980-N enters sleep mode, and less than 1-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 Short-CircuitProtection(CurrentLimit) Theinternalcurrent-limitcircuitisusedtoprotecttheLDOagainsthigh-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. If a current limit occurs and the resulting output voltage is low, excessive power may be dissipated across the LDO resulting in a thermal shutdown of the output. A foldback feature limits the short-circuit current to protect the regulator from damage under all load conditions. If OUT is forced below 0 V before EN goes high and the load current required exceeds thefoldbackcurrentlimit,thedevicemaynotstartupcorrectly. 7.3.7 ThermalProtection The LP2980-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 cycles on and off at a high rate when thermal shutdown is reached until the power dissipation is reduced. The internal protection circuitry of the LM2980-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. 7.4 Device Functional Modes 7.4.1 OperationwithV +1V≤ V < 16V OUT(TARGET) IN The device operates if the input voltage is equal to, or exceeds, V + 0.6 V. At input voltages below the OUT(TARGET) minimumV requirement,thedevicedoesnotoperatecorrectlyandoutputvoltagemaynotreachtargetvalue.

LP2980-N www.ti.com SNOS733P–APRIL2000–REVISEDSEPTEMBER2016 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 LP2980-N is a linear voltage regulator operating from 2.1 V to 16 V on the input and regulates voltages between 2.5 V to 5 V with 0.5% accuracy and 50-mA maximum output current. Efficiency is defined by the ratio of output voltage to input voltage because the LP2980-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, startup, noise, power supply rejection ratio (PSRR), or any other transient specification is required, then the design becomes more challenging.

The efficiency of the LP2980-NinthisconfigurationisV /V =66.7%.Toachievethesmallestformfactor,theSOT-23packageis OUT IN selected. Input and output capacitors are selected in accordance with the Output Capacitor Recommendation section. With an efficiency of 66.7% and a 50-mA maximum load, the internal power dissipation is 85 mW, which corresponds to a 14.9°C junction temperature rise for the SOT-23 package. With an 85°C maximum ambient temperature,thejunctiontemperatureisat99.9°C. 8.2.2.1 OutputCapacitorRecommendation Like any low-dropout regulator, the LP2980-N requires an output capacitor to maintain regulator loop stability. This capacitor must be selected to meet the requirements of minimum capacitance and equivalent series resistance (ESR) range. It is not difficult to find capacitors which meet the criteria of the LP2980-N, as the acceptablecapacitanceandESRrangesarewiderthanformostotherLDOs. In general, the capacitor value must be at least 1 μF (over the actual ambient operating temperature), and the ESR must be within the range indicated in Figure 31, Figure 32, and Figure 33. It should be noted that, although amaximumESRisshowninthesefigures,itisveryunlikelytofindacapacitorwithanESRthathigh. 8.2.2.1.1 TantalumCapacitors Surface-mountable solid tantalum capacitors offer a good combination of small physical size for the capacitance value,andanESRintherangeneededbytheLP2980-N. The results of testing the LP2980-N stability with surface-mount solid tantalum capacitors show good stability with values of at least 1 μF. The value can be increased to 2.2 μF (or more) for even better performance, includingtransientresponseandnoise. Small value tantalum capacitors that have been verified as suitable for use with the LP2980-N are shown in Table1.Capacitancevaluescanbeincreasedwithoutlimit. 8.2.2.1.2 AluminumElectrolyticCapacitors Although probably not a good choice for a production design, because of relatively large physical size, an aluminum electrolytic capacitor can be used in the design prototype for an LP2980-N regulator. A value of at least 1 μF should be used, and the ESR must meet the conditions of Figure 31, Figure 32, and Figure 33. If the operating temperature drops below 0°C, the regulator may not remain stable, as the ESR of the aluminum electrolyticcapacitorwillincreaseandmayexceedthelimitsindicatedinFigure31,Figure32,andFigure33.

However, they sometimes have ESR values lower than the minimum required by the LP2980-N, and relatively large capacitance change with temperature.

During normal operation (where the input voltage is higher than the output)thisdiodeisreversebiased(seeFigure34). VIN VOUT PNP GND Figure34. LP2980-NReverseCurrentPath However, if the input voltage is more than a V below the output voltage, this diode will turn on and current will BE flow into the regulator output. In such cases, a parasitic SCR can latch which will allow a high current to flow into theV pinandoutthegroundpin,whichcandamagethepart. IN The internal diode can also be turned on if the input voltage is abruptly stepped down to a voltage which is a V BE belowtheoutputvoltage. In any application where the output voltage may be higher than the input voltage, an external Schottky diode must be connected from V to V (cathode on V , anode on V , see Figure 35), to limit the reverse voltage IN OUT IN OUT acrosstheLP2980-Nto0.3V(seeAbsoluteMaximumRatings). 18 SubmitDocumentationFeedback Copyright©2000–2016,TexasInstrumentsIncorporated ProductFolderLinks:LP2980-N

AddingExternalSchottkyDiodeProtection 8.2.2.3 ON/OFF InputOperation The LP2980-N is shut off by pulling the ON/OFF input low, and turned on by driving the input high. If this feature is not to be used, the ON/OFF input must be tied to IN to keep the regulator on at all times (the ON/OFF input mustnotbeleftfloating). To ensure proper operation, the signal source used to drive the ON/OFF input must be able to swing above and below the specified turn-on and turn-off voltage thresholds which ensure an ON or OFF state (see Electrical Characteristics). The ON/OFF signal may come from either a totem-pole output, or an open-collector output with a pull-up resistor to the LP2980-N input voltage or another logic supply. The high-level voltage may exceed the LP2980-N input voltage,butmustremainwithintheabsolutemaximumratingsfortheON/OFF pin. It is also important that the turn-on and turn-off voltage signals applied to the ON/OFF input have a slew rate that isgreaterthan40mV/μs. NOTE The regulator shutdown function will not operate correctly if a slow-moving signal is used todrivetheON/OFF input. 8.2.2.4 IncreasingOutputCurrent The LP2980-N can be used to control higher-current regulators, by adding an external PNP pass transistor. With the PNP transistors shown in Figure 36, the output current can be as high as 400 mA, as long as the input voltageisheldwithintheSafeOperationBoundaryCurvesshownbelowinFigure37. To ensure regulation, the minimum input voltage of this regulator is 6 V. This headroom is the sum of the V of BE theexternaltransistorandthedropoutvoltageoftheLP2980-N.

SafeOperationBoundaryCurvesforFigure36 With limited input voltage range, the LP2980-N can control a 3.3-V, 3-A regulator with the use of a high current- gain external PNP pass transistor as shown in Figure 38. If the regulator is to be loaded with the full 3 A, heat sinking will be required on the pass transistor to keep it within its rated temperature range. See Figure 39. For best load regulation at the high load current, the LP2980-N output voltage connection should be made as close totheloadaspossible. 20 SubmitDocumentationFeedback Copyright©2000–2016,TexasInstrumentsIncorporated ProductFolderLinks:LP2980-N

LP2980-N www.ti.com SNOS733P–APRIL2000–REVISEDSEPTEMBER2016 9 Power Supply Recommendations The LP2980-N is designed to operate from an input voltage supply range between 2.1 V and 16 V. The input voltage range provides adequate headroom for the device to have a regulated output. This input supply must be well regulated. If the input supply is noisy, additional input capacitors with low ESR can help improve the output noiseperformance. 10 Layout 10.1 Layout Guidelines For best overall performance, place all circuit components on the same side of the circuit board and as near as practical to the respective LDO pin connections. Place ground return connections to the input and output capacitors,andtotheLDOgroundpinascloseaspossibletoeachother,connectedbyawide,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 thereby reduces load-current transients, minimizes noise, and increases circuit stability. 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 most applications, this groundplaneisnecessarytomeetthermalrequirements. 10.2 Layout Example VIN VOUT Input IN OUT Output Capacitor Capacitor GND Ground ON/OFF ON/OFF NC Figure41.
