This circuit ensures that the device does not exhibit any unpredictable behaviorwhenthesupplyvoltageislowerthantheoperationalrangeoftheinternalcircuitry,V . IN(min) 7.3.2 Shutdown The enable pin (EN) is active high. Enable the device by forcing the EN pin to exceed V (1.7 V, minimum). EN(high) Turn off the device by forcing the EN pin to drop below 0.7 V. If shutdown capability is not required, connect EN toIN. 7.3.3 FoldbackCurrentLimit The TPS730 features internal current limiting and thermal protection. During normal operation, the TPS730 limits output current to approximately 400 mA. When current limiting engages, the output voltage scales back linearly until the overcurrent condition ends.

TPS730 www.ti.com SBVS054J–NOVEMBER2004–REVISEDAPRIL2015 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 TPS730 family of low-dropout (LDO) regulators has been optimized for use in noise-sensitive battery- operated equipment. The device features extremely low dropout voltages, high PSRR, ultra-low output noise, low quiescent current (170 μA typically), and enable-input to reduce supply currents to less than 1 μA when the regulatoristurnedoff. 8.1.1 AdjustableOperation The output voltage of the TPS73001 adjustable regulator is programmed using an external resistor divider as showninFigure17.TheoutputvoltageiscalculatedusingEquation1: § R · V V u¨1(cid:14) 1 ¸ OUT REF © R2 ¹ Where: • V =1.225Vtypical(theinternalreferencevoltage) (1) REF Resistors R and R should be chosen for approximately 50-μA divider current. Lower value resistors can be 1 2 used for improved noise performance, but the solution consumes more power. Higher resistors values can cause accuracy issues and other problems. The recommended design procedure is to choose R = 30.1 kΩ to set the 2 dividercurrentat50μA,C =15pFforstability,andthencalculateR usingEquation2: 1 1 V R = OUT -1 ´R 1 V 2 REF (2) To improve the stability of the adjustable version, TI suggests placing a small compensation capacitor between OUTandFB.Foroutputvoltages< 1.8V,thevalueofthiscapacitorshouldbe100pF.Foroutputvoltages >1.8 V,useEquation3tocalculatetheapproximatevalueofthiscapacitor. (3u10(cid:16)7)u(R (cid:14)R ) C 1 2 1 (R1uR2) (3) Figure 17 shows the suggested value of this capacitor for several resistor ratios. If this capacitor is not used (such as in a unity-gain configuration) or if an output voltage < 1.8 V is chosen, then the minimum recommended outputcapacitoris4.7μFinsteadof2.2 μF.

TPS730 SBVS054J–NOVEMBER2004–REVISEDAPRIL2015 www.ti.com Application Information (continued) 8.1.2 CapacitorRecommendations Low equivalent series resistance (ESR) capacitors should be used for the input, output, noise reduction, and bypass capacitors. Ceramic capacitors with X7R and X5R dielectrics are preferred. These dielectrics offer more stable characteristics. Ceramic X7R capacitors offer improved overtemperature performance, while ceramic X5R capacitorsaremorecost-effectiveandareavailableinhighervalues. 8.1.3 InputandOutputCapacitorRequirements A 0.1-μF or larger ceramic input bypass capacitor, connected between IN and GND and located close to the TPS730, is required for stability and improves transient response, noise rejection, and ripple rejection. A higher- value input capacitor may be necessary if large, fast-rise-time load transients are anticipated or the device is locatedseveralinchesfromthepowersource. Like most low-dropout regulators, the TPS730 requires an output capacitor connected between OUT and GND to stabilize the internal control loop. The minimum recommended capacitance is 2.2 μF. Any 2.2-μF or larger ceramic capacitor is suitable, provided the capacitance does not vary significantly over temperature. If load current is not expected to exceed 100 mA, a 1-μF ceramic capacitor can be used. If a feed-forward capacitor is not used (such as in a unity-gain configuration) or if an output voltage less than 1.8 V is chosen, then the minimum recommended output capacitor is 4.7 μF instead of 2.2 μF. Table 2 lists the recommended output capacitorsizesforseveralcommonconfigurations. Table2.OutputCapacitorSizing CONDITION C (µF) OUT V <1.8VorC =0nF 4.7 OUT FF V >1.8V,I >100mA 2.2 OUT OUT V >1.8V,I <100mA 1 OUT OUT 8.1.4 NoiseReductionandFeed-ForwardCapacitorRequirements The internal voltage reference is a key source of noise in an LDO regulator. The TPS730 has an NR pin which is connected to the voltage reference through a 250-kΩ internal resistor. The 250-kΩ internal resistor, in conjunction with an external bypass capacitor connected to the NR pin, creates a low-pass filter to reduce the voltage reference noise and, therefore, the noise at the regulator output. In order for the regulator to operate properly, the current flow out of the NR pin must be at a minimum, because any leakage current creates an IR drop across the internal resistor thus creating an output error. Therefore, the bypass capacitor must have minimal leakage current. The bypass capacitor should be no more than 0.1 μF to ensure that it is fully charged duringthequick-starttimeprovidedbytheinternalswitchshownintheFunctionalBlockDiagramsection. As an example, the TPS73018 exhibits only 33 μV of output voltage noise using a 0.01-μF ceramic bypass RMS capacitoranda2.2-μFceramicoutputcapacitor.Notethattheoutputstartsupslowerasthebypasscapacitance increases due to the RC time constant at the NR pin that is created by the internal 250-kΩ resistor and external capacitor. A feed-forward capacitor is recommended to improve the stability of the device. If R = 30.1 kΩ, set C to 15 pF 2 1 for optimal performance. For voltages less than 1.8 V, the value of this capacitor should be 100 pF. For voltages greaterthan1.8V,theapproximatevalueofthiscapacitorcanbecalculatedasshowninEquation3. 8.1.5 ReverseCurrentOperation The TPS730 PMOS-pass transistor has a built-in back diode that conducts reverse current when the input voltage drops below the output voltage (for example, during power-down). Current is conducted from the output to the input and is not internally limited. If extended reverse voltage operation is anticipated, external limiting might be appropriate. If extended reverse voltage operation in anticipated, external limiting to 5% of the rated outputcurrentisrecommended. 12 SubmitDocumentationFeedback Copyright©2004–2015,TexasInstrumentsIncorporated ProductFolderLinks:TPS730

TPS730 www.ti.com SBVS054J–NOVEMBER2004–REVISEDAPRIL2015 9 Power Supply Recommendations These devices are designed to operate from an input voltage supply range from 2.7 V to 5.5 V. The input voltage range must provide adequate headroom in order for the device to have a regulated output. This input supply must be well-regulated and stable. A 0.1-µF input capacitor is required for stability; if the input supply is noisy, additionalinputcapacitorswithlowESRcanhelpimprovetheoutputnoiseperformance. 10 Layout 10.1 Layout Guidelines Layout is a critical part of good power-supply design. There are several signal paths that conduct fast-changing currents or voltages that can interact with stray inductance or parasitic capacitance to generate noise or degrade the power-supply performance. To help eliminate these problems, the IN pin should be bypassed to ground with alowESRceramicbypasscapacitorwithanX5RorX7Rdielectric. Equivalent series inductance (ESL) and equivalent series resistance (ESR) must be minimized to maximize performanceandensurestability.Everycapacitor(C ,C ,C ,C )mustbeplacedascloseaspossibleto IN OUT NR/SS FF thedeviceandonthesamesideofthePCBastheregulatoritself. DonotplaceanyofthecapacitorsontheoppositesideofthePCBfromwheretheregulatorisinstalled.Theuse of vias and long traces is strongly discouraged because these circuits may impact system performance negatively,andevencauseinstability. 10.1.1 BoardLayoutRecommendationstoImprovePSRRandNoisePerformance To improve AC measurements like PSRR, output noise, and transient response, TI recommends designing the board with separate ground planes for V and V , with each ground plane connected only at the GND pin of IN OUT the device. In addition, the ground connection for the bypass capacitor should connect directly to the GND pin of thedevice. 10.2 Layout Example Output Ground Output Plane Input Plane IN OUT GND FB EN NR Input Ground NR and FB Ground Denotes via Figure23.

TPS730 SBVS054J–NOVEMBER2004–REVISEDAPRIL2015 www.ti.com 10.3 Thermal Considerations Thermal protection disables the output when the junction temperature rises to approximately 165°C, allowing the device to cool. When the junction temperature cools to approximately 140°C, the output circuitry is again enabled. Depending on power dissipation, thermal resistance, and ambient temperature, the thermal protection circuit may cycle on and off. This cycling limits regulator dissipation, protecting the device from damage as a resultofoverheating. Any tendency to activate the thermal protection circuit indicates excessive power dissipation or an inadequate heatsink.Forreliableoperation,junctiontemperaturemustbelimitedto125°Cmaximum.Toestimatethemargin of safety in a complete design (including heatsink), increase the ambient temperature until the thermal protection istriggered;useworst-caseloadsandsignalconditions. The TPS730 internal protection circuitry is designed to protect against overload conditions. This circuitry is not intended to replace proper heatsinking. Continuously running the TPS730 into thermal shutdown degrades devicereliability. 10.4 Power Dissipation Specified regulator operation is assured to a junction temperature of +125°C; the maximum junction temperature should be restricted to +125°C under normal operating conditions. This restriction limits the power dissipation the regulator can handle in any given application. To ensure the junction temperature is within acceptable limits, calculate the maximum allowable dissipation, P , and the actual dissipation, P , which must be less than or D(max) D equaltoP . D(max) ThemaximumpowerdissipationlimitisdeterminedusingEquation4: T max(cid:16) T P J A D(max) R 4JA Where: • Tmaxisthemaximumallowablejunctiontemperature.

(4) A TheregulatordissipationiscalculatedusingEquation5: PD (VIN (cid:16) VOUT)uIOUT (5) Power dissipation resulting from quiescent current is negligible. Excessive power dissipation triggers the thermal protectioncircuit. Figure 24 shows the maximum ambient temperature versus the power dissipation of the TPS730. This figure assumes the device is soldered on a JEDEC standard, high-K layout with no airflow over the board. Actual board thermal impedances vary widely. If the application requires high power dissipation, having a thorough understanding of the board temperature and thermal impedances is helpful to ensure the TPS730 does not operateaboveajunctiontemperatureof125°C. 125 DBV Package C) YZQ Package q e ( ur at er 100 p m e T nt e bi m A 75 m u m xi a M 50 0 0.1 0.2 0.3 0.4 0.5 Power Dissapation (W) Figure24.
