Each • FastStart-UpTime(63m s) device in the family is stable, with a small 1-m F • StableWithAny1-m FCeramicCapacitor ceramic capacitor on the output. The family uses an advanced, proprietary BiCMOS fabrication process to • ExcellentLoad/LineTransient yield extremely low dropout voltages (e.g., 38 mV at • VeryLowDropoutVoltage 100 mA, TPS79147). Each device achieves fast (38mVatFullLoad,TPS79147) start-up times (approximately 63 m s with a 0.001-m F • 5-PinSOT23(DBV)Package bypass capacitor) while consuming very low quiescent current (170 m A typical). Moreover, when • TPS792xxProvidesENOptions the device is placed in standby mode, the supply current is reduced to less than 1 m A. The TPS79118 APPLICATIONS exhibits approximately 15 m V of output voltage RMS • VCOs noise with a 0.1-m F bypass capacitor. Applications • RF with analog components that are noise sensitive, such as portable RF electronics, benefit from the • Bluetooth™,WirelessLAN high-PSRR and low-noise features as well as the fast responsetime.

SGLS161A–APRIL2003–REVISEDJUNE2008 APPLICATION INFORMATION The TPS791xx family of low-dropout (LDO) regulators have been optimized for use in noise-sensitive battery-operated equipment. The device features extremely low dropout voltages, high PSRR, ultralow output noise, low quiescent current (170 m A typically), and enable-input to reduce supply currents to less than 1 m A whentheregulatoristurnedoff. AtypicalapplicationcircuitisshowninFigure33. TPS791xx 1 VI IN 4 BYPASS 5 OUT VO 0.1 m F 3 0.01 m F EN + 1 m F GND 2 Figure33.TypicalApplicationCircuit External Capacitor Requirements A 0.1-m F or larger ceramic input bypass capacitor, connected between IN and GND and located close to the TPS791xx, is required for stability and to improve transient response, noise rejection, and ripple rejection. A higher-value electrolytic input capacitor may be necessary if large, fast-rise-time load transients are anticipated andthedeviceislocatedseveralinchesfromthepowersource. Like all low dropout regulators, the TPS791xx requires an output capacitor connected between OUT and GND to stabilize the internal control loop. The minimum recommended capacitance is 1 m F. Any 1-m F or larger ceramic capacitorissuitable.Thedeviceisalsostablewitha0.47-m Fceramiccapacitorwithatleast75mΩofESR. The internal voltage reference is a key source of noise in an LDO regulator. The TPS791xx has a BYPASS 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 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 m V of output voltage noise using a 0.1-m F ceramic RMS bypass capacitor and a 1-m F ceramic output capacitor. Note that the output starts up slower as the bypass capacitance increases due to the RC time constant at the bypass pin that is created by the internal 250 kΩ resistorandexternalcapacitor. Board Layout Recommendation To Improve PSRR And Noise Performance ToimproveacmeasurementslikePSRR,outputnoise,and transient response, it is recommended that the board be designed with separate ground planes for V and V , with each ground plane connected only at the ground IN OUT pin of the device. In addition, the ground connection for the bypass capacitor should connect directly to the groundpinofthedevice.

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) Themaximumpower-dissipationlimitisdeterminedusingthefollowingequation: T max(cid:1)T P (cid:2) J A D(max) R (cid:1)JA (1) Where: T maxisthemaximumallowablejunctiontemperature.

Excessive power dissipation triggers the thermal protectioncircuit. Programming the TPS79101 Adjustable LDO Regulator The output voltage of the TPS79101 adjustable regulator is programmed using an external resistor divider as showninFigure34.Theoutputvoltageiscalculatedusing: (cid:4) R1(cid:5) VO(cid:3)Vref(cid:1) 1(cid:2)R2 (3) Where: V =1.2246Vtyp(theinternalreferencevoltage) ref Resistors R1 and R2 should be chosen for approximately 50-m A divider current. Lower value resistors can be used for improved noise performance, but the solution consumes more power. Higher resistor values should be avoided as leakage current into/out of FB across R1/R2 creates an offset voltage that artificially increases/decreases the feedback voltage and thus erroneously decreases/increases V . The recommended O design procedure is to choose R2 = 30.1 kΩ to set the divider current at 50 m A, C1 = 15 pF for stability, and then calculateR1using: (cid:4)V (cid:5) O R1(cid:3) (cid:2)1 (cid:1)R2 V ref (4) In order to improve the stability of the adjustable version, it is suggested that a small compensation capacitor be placed between OUT and FB. For voltages <1.8 V, the value of this capacitor should be 100 pF. For voltages>1.8V,theapproximatevalueofthiscapacitorcanbecalculatedas: (3(cid:1)10(cid:3)7)(cid:1)(R1 (cid:2) R2) C1 (cid:4) (R1(cid:1)R2) (5) The suggested value of this capacitor for several resistor ratios is shown in the table below. 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 recommendedoutputcapacitoris2.2m Finsteadof1m F. 12 SubmitDocumentationFeedback Copyright©2003–2008,TexasInstrumentsIncorporated ProductFolderLink(s):TPS79101-EP TPS79118-EPTPS79133-EP TPS79147-EP

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. The TPS791xx features internal current limiting and thermal protection. During normal operation, the TPS791xx limits output current to approximately 400 mA. When current limiting engages, the output voltage scales back linearly until the overcurrent condition ends. While current limiting is designed to prevent gross device failure, care should 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 it down. Once the device has cooled down to below approximately 140°C, regulator operation resumes.
