Each device in the family is stable with a RMS small, 1-μF ceramic capacitor on the output. The • FastStart-UpTime(50 μs) family uses an advanced, proprietary BiCMOS • StableWitha1-μFCeramicCapacitor fabrication process to yield extremely low dropout • ExcellentLoadandLineTransientResponse voltages (for example, 250 mV at 1 A). Each device achievesfaststart-uptimes(approximately50μswith • VeryLowDropoutVoltage(250mVatFullLoad, a 0.001-μF bypass capacitor) while consuming very TPS79630) low quiescent current (265 μA typical). Moreover, • 3× 3VSON PowerPAD™,SOT223-6,and when the device is placed in standby mode, the TO-263Packages supply current is reduced to less than 1 μA. The TPS79630 exhibits approximately 40 μV of output RMS 2 Applications voltage noise at 3.0-V output, with a 0.1-μF bypass capacitor. Applications with analog components that • RF:VCOs,Receivers,ADCs are noise sensitive, such as portable RF electronics, • Audio benefit from the high PSRR, low noise features, and • Bluetooth®,WirelessLAN needfastresponsetime. • CellularandCordlessTelephones DeviceInformation(1) • HandheldOrganizers,PDAs PARTNUMBER PACKAGE BODYSIZE(NOM) VSON(8) 3.00mm×3.00mm TPS796 SOT-223(6) 6.50mm×3.50mm TO-263(5) 10.16mm×8.42mm (1) For all available packages, see the orderable addendum at theendofthedatasheet.

High PSRR is provided by a high-gain, high- bandwidth error loop with good supply rejection at very low headroom (V – V ). A noise-reduction pin is IN OUT provided to bypass noise generated by the band-gap reference and to improve PSRR, while a quick-start circuit quickly charges this capacitor at start-up. All versions have thermal and overcurrent protection, and are fully specifiedfrom–40°Cto125°C. 7.2 Functional Block Diagrams IN OUT UVLO Current Sense ILIM SHUTDOWN GND R 1 FB EN UVLO R 2 Thermal Shutdown Quickstart External to the device Bandgap V V Reference REF IN 1.225 V 250 kW Figure22.

When shutdowncapabilityisnotrequired,ENcanbeconnectedtoIN. 7.3.2 Start-Up The TPS796 uses a start-up circuit to quickly charge the noise reduction capacitor, C , if present (see the NR Functional Block Diagrams). This circuit allows for the combination of very low output noise and fast start-up times. The NR pin is high impedance so a low leakage C capacitor must be used; most ceramic capacitors are NR appropriateforthisconfiguration. For the fastest start-up, apply V first, and then drive the enable pin (EN) high. If EN is tied to IN, start-up is IN somewhatslower.ToensurethatC isfullychargedduringstart-up,usea0.1-μForsmallercapacitor. NR 7.3.3 UndervoltageLockout(UVLO) The TPS796 uses an undervoltage lockout circuit to keep the output shut off until internal circuitry is operating properly. The UVLO circuit has approximately 100 mV of hysteresis to help reject input voltage drops when the regulatorfirstturnson. 7.3.4 RegulatorProtection The TPS796xx 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 mightbeappropriate. The TPS796xx features internal current limiting and thermal protection. During normal operation, the TPS796xx limits output current to approximately 2.8 A. 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. If the temperature of the device exceeds approximately 165°C (T ), thermal-protection circuitry shuts it down. Once the device has cooled down sd tobelowapproximately140°C,regulatoroperationresumes. 12 SubmitDocumentationFeedback Copyright©2002–2015,TexasInstrumentsIncorporated ProductFolderLinks:TPS79601 TPS79613 TPS79618 TPS79625TPS79628 TPS79630 TPS79633 TPS79650

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 8.1 Application Information The TPS796xx family of low-dropout (LDO) regulators has been optimized for use in noise-sensitive equipment. The device features extremely low dropout voltages, high PSRR, ultralow output noise, low quiescent current (265μAtypically),andenableinputtoreducesupplycurrentstolessthan1 μAwhentheregulatoristurnedoff. 8.2 Typical Application AtypicalapplicationcircuitisshowninFigure24.

Provide an input supply with adequate headroom to account for dropout and output current to account for the GNDterminalcurrent,andpowertheload. 8.2.2.1 InputandOutputCapacitorRequirements A 2.2-μF or larger ceramic input bypass capacitor, connected between IN and GND and located close to the TPS796xx, 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 and the deviceislocatedseveralinchesfromthepowersource. Like most low dropout regulators, the TPS796xx requires an output capacitor connected between OUT and GND to stabilize the internal control loop. The minimum recommended capacitor is 1 μF. Any 1-μF or larger ceramic capacitorissuitable. 14 SubmitDocumentationFeedback Copyright©2002–2015,TexasInstrumentsIncorporated ProductFolderLinks:TPS79601 TPS79613 TPS79618 TPS79625TPS79628 TPS79630 TPS79633 TPS79650

The TPS796xx 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 in order to ensure that it is fully chargedduringthequickstarttimeprovidedbytheinternalswitchshowninthefunctionalblockdiagram. For example, the TPS79630 exhibits 40 μV of output voltage noise using a 0.1-μF ceramic bypass capacitor RMS and a 10-μF ceramic output capacitor. The output starts up slower as the bypass capacitance increases due to theRCtimeconstantatthebypasspinthatiscreatedbytheinternal250-kΩresistorandexternalcapacitor. 8.2.2.3 DropoutVoltage The TPS796 uses a PMOS pass transistor to achieve a low dropout voltage. When (V – V ) is less than the IN OUT dropout voltage (V ), the PMOS pass device is in its linear region of operation and r of the PMOS pass DO DS(on) element is the input-to-output resistance. Because the PMOS device behaves like a resistor in dropout, V DO approximatelyscaleswiththeoutputcurrent. As with any linear regulator, PSRR degrades as (V – V ) approaches dropout. This effect is illustrated in IN OUT Figure9 throughFigure11inTypicalCharacteristics.

The input voltage range provides adequate headroom in order for the device to have a regulated output. This input supply is well-regulated and stable. If the input supply is noisy, additional input capacitors with low ESR can help improvetheoutputnoiseperformance. 10 Layout 10.1 Layout Guidelines 10.1.1 BoardLayoutRecommendationtoImprovePSRRandNoisePerformance To improve AC measurements like PSRR, output noise, 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 IN OUT ground pin of the device. In addition, the ground connection for the bypass capacitor should connect directly to thegroundpinofthedevice. 10.1.2 RegulatorMounting The tab of the SOT223-6 package is electrically connected to ground. For best thermal performance, the tab of the surface-mount version should be soldered directly to a circuit-board copper area. Increasing the copper area improvesheatdissipation. Solder pad footprint recommendations for the devices are presented in an application bulletin Solder Pad RecommendationsforSurface-MountDevices,SBFA015,availablefromtheTIwebsite(www.ti.com).

Power dissipation of the device depends on input voltage and load conditions and can be calculated using Equation4: P (cid:11)V (cid:16)V (cid:12)uI D IN OUT OUT (4) Power dissipation can be minimized and greater efficiency can be achieved by using the lowest possible input voltagenecessarytoachievetherequiredoutputvoltageregulation. On the VSON (DRB) package, the primary conduction path for heat is through the exposed pad to the printed circuit board (PCB). The pad can be connected to ground or be left floating; however, it should be attached to an appropriate amount of copper PCB area to ensure the device does not overheat. On both SOT-223 (DCQ) and TO-263 (KTT) packages, the primary conduction path for heat is through the tab to the PCB. That tab should be connected to ground. The maximum junction-to-ambient thermal resistance depends on the maximum ambient temperature, maximum device junction temperature, and power dissipation of the device and can be calculated usingEquation5: (cid:11)(cid:14)125qC(cid:16)T (cid:12) R A TJA P D ' (5) Knowing the maximum R , the minimum amount of PCB copper area needed for appropriate heatsinking can θJA beestimatedusingFigure30.
