The RMS device is stable, with a small 1-µF ceramic capacitor • FastStart-UpTime(63 µs) on the output. The TPS791 uses an advanced, • StableWithAny1-µFCeramicCapacitor proprietary BiCMOS fabrication process to yield • ExcellentLoad,LineTransient extremely low dropout voltages (for example, 38 mV at 100 mA, TPS79147). This device achieves fast • VeryLowDropoutVoltage(38mVatFullLoad, start-up times (approximately 63 µs with a 0.001-µF TPS79147) bypass capacitor) while consuming very low • 5-PinSOT23(DBV)Package quiescent current (170 µA typical). Moreover, when • TPS792xxProvidesENOptions the device is placed in standby mode, the supply current is reduced to less than 1 µA. The TPS79118 2 Applications exhibits approximately 15 µV of output voltage RMS noise with a 0.1-µF bypass capacitor. Applications • PoweringVCOsandPLLs with analog components that are noise sensitive, • BluetoothandWirelessLAN such as portable RF electronics, benefit from the high • PortableandBatteryOperated PSRR and low noise features as well as the fast responsetime.

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 .

Lower value resistors can be used for improved noise performance, but the solution consumes more power.

TPS79101AdjustableLDORegulatorProgramming 7.3.3 RegulatorProtection The TPS791 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 may beappropriate. The TPS791 features internal current limiting and thermal protection. During normal operation, the TPS791 limits output current to approximately 400 mA. When current limiting engages, the output voltage scales back linearly until the overcurrent condition ends. Although current limiting is designed to prevent gross device failure, care must be taken not to exceed the power dissipation ratings of the package or the absolute maximum voltage ratings of the device. If the temperature of the device exceeds approximately 165°C, thermal-protection circuitry shuts the device down. When the device cools down to below approximately 140°C, regulator operation resumes. 14 SubmitDocumentationFeedback Copyright©2001–2018,TexasInstrumentsIncorporated ProductFolderLinks:TPS791

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 8.1 Application Information TheTPS791low-dropout(LDO)regulatorisoptimizedforuseinnoise-sensitivebattery-operatedequipment.The device features extremely low dropout voltages, high PSRR, ultralow output noise, low quiescent current (170 µA typically), and an active-low, enable input to reduce supply currents to less than 1 µA when the regulator is turnedoff. 8.1.1 ExternalCapacitorRequirements A 0.1-µF or larger ceramic input bypass capacitor, connected between IN and GND and located close to the TPS791,isrequiredforstabilityandtoimprovetransientresponse,noiserejection,andripplerejection.Ahigher- value electrolytic input capacitor may be necessary if large, fast-rise-time load transients are anticipated and the deviceislocatedseveralinchesfromthepowersource. Like all low dropout regulators, the TPS791 requires an output capacitor connected between OUT and GND to stabilize the internal control loop. The minimum recommended capacitance is 1 µF. Any 1-µF or larger ceramic capacitorissuitable.Thedeviceisalsostablewitha0.47-µFceramiccapacitorwithatleast75mΩ ofESR. The internal voltage reference is a key source of noise in an LDO regulator. The TPS791 has a BYPASS pin that 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 BYPASS 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 BYPASS 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 minimalleakagecurrent. For example, the TPS79118 exhibits approximately 15 µV of output voltage noise using a 0.1-µF ceramic RMS bypass capacitor and a 1-µF ceramic output capacitor. The output starts up slower as the bypass capacitance increases because of the RC time constant at the bypass pin that is created by the internal 250-kΩ resistor and externalcapacitor. 8.2 Typical Application Figure35showsatypicalapplicationcircuit.

TPS791 SLVS325D–MARCH2001–REVISEDFEBRUARY2018 www.ti.com 9 Power Supply Recommendations This device is 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, bypass the IN pin to ground with a low ESR ceramicbypasscapacitorwithanX5RorX7Rdielectric. Equivalent series inductance (ESL) and equivalent series resistance (ESR) must be minimized to maximize performance and ensure stability. Every capacitor (C , C , C , and C ) must be placed as close as IN OUT BYPASS 1 possibletothedeviceandonthesamesideofthePCBastheregulatoritself. Do not place any capacitors on the opposite side of the PCB from where the regulator is installed. The use of vias and long traces is strongly discouraged because these circuits can impact system performance negatively, andevencauseinstability. 10.1.1 BoardLayoutRecommendationtoImprovePSRRandNoisePerformance To improve ac measurements such as PSRR, output noise, and transient response, TI recommends that the board be designed with separate ground planes for V and V , with each ground plane connected only at the IN OUT ground pin of the device. In addition, connect the ground connection for the bypass capacitor directly to the groundpinofthedevice. 10.2 Layout Example Output Ground Output Plane Input Plane IN OUT GND FB EN(1) BYPASS Input Ground NR and FB Ground Denotes via (1) TheENpinisactivelow.

(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
