TPS793 SLVS348L–JULY2001–REVISEDMAY2015 www.ti.com 7.3 Feature Description 7.3.1 UndervoltageLockout(UVLO) The TPS793 uses an undervoltage lockout (UVLO) circuit that disables the output until the input voltage is greater than the rising UVLO voltage. 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 TPS793 features internal current limiting and thermal protection. During normal operation, the TPS793 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 ratingsofthedevice. 7.3.4 ThermalProtection 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 TPS793 internal protection circuitry is designed to protect against overload conditions. This circuitry is not intended to replace proper heatsinking. Continuously running the TPS793 into thermal shutdown degrades devicereliability. 7.3.5 ReverseCurrentOperation The TPS793 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 to 5%oftheratedoutputcurrentisrecommended. 12 SubmitDocumentationFeedback Copyright©2001–2015,TexasInstrumentsIncorporated ProductFolderLinks:TPS793

TPS793 SLVS348L–JULY2001–REVISEDMAY2015 www.ti.com 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 TPS793 family of LDO regulators has 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 (170μAtypically),andenable-inputtoreducesupplycurrentstolessthan1 μAwhentheregulatoristurnedoff. 8.1.1 AdjustableOperation The output voltage of the TPS79301 adjustable regulator is programmed using an external resistor divider as showninFigure23.TheoutputvoltageiscalculatedusingEquation1: æ R ö VOUT = VREF´ç1+R1÷ è 2ø where: • V =1.2246Vtyp(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: FF 1 æV ö R1 =çVOUT -1÷´R2 è REF ø (2) To improve the stability of the adjustable version, it is suggested that a small compensation capacitor be placed between OUT and FB. For output voltages less than 1.8 V, the value of this capacitor should be 100 pF. For output voltages greater than 1.8 V, the approximate value of this capacitor can be calculated as shown in Equation3: (3´10-7)´(R + R ) C = 1 2 FF (R ´R ) 1 2 (3) The suggested value of this capacitor for several resistor ratios is shown in the table in Figure 23. If this capacitorisnotused(suchasinaunity-gainconfiguration)orifanoutputvoltagelessthan1.8Vischosen,then theminimumrecommendedoutputcapacitoris4.7μFinsteadof2.2 μF.

An input capacitor of 0.1 µF is used as the battery is connected to the input through a via and a short 10-mil (0.01-in) trace. An output capacitor of 10 µF is used to provide optimal response time for the load transient. Verify that the maximum junction temperature is not exceed by referring to Figure30. 8.2.2.1 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 over-temperature performance, while ceramic X5R capacitorsaremorecost-effectiveandareavailableinhighervalues. 8.2.2.2 InputandOutputCapacitorRequirements A 0.1-μF or larger ceramic input bypass capacitor, connected between IN and GND and located close to the TPS793, 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 TPS793 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 1.0-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 3 lists the recommended output capacitorsizesforseveralcommonconfigurations. Copyright©2001–2015,TexasInstrumentsIncorporated SubmitDocumentationFeedback 15 ProductFolderLinks:TPS793

The TPS793 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 duringthequickstarttimeprovidedbytheinternalswitchshownintheFunctionalBlockDiagrams. As an example, the TPS79328 exhibits only 32 μV of output voltage noise using a 0.1-μF ceramic bypass RMS capacitor and a 2.2-μF ceramic output capacitor. Note that the output starts up slower as the bypass capacitance increases due to the RC time constant at the NR pin that is created by the internal 250-kΩ resistor and external capacitor. This RC time constant is affected by the quick-start circuit, especially for values near or below 10 nF. SeeFigure13foracomparisonsofC capacitorsandstartuptimes. NR 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.

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.

LayoutExample(DBVPackage) 10.3 Power Dissipation The ability to remove heat from the die is different for each package type, presenting different considerations in the printed circuit board (PCB) layout. The PCB area around the device that is free of other components moves the heat from the device to the ambient air. Performance data for JEDEC low- and high-K boards are given in Thermal Information. Using heavier copper increases the effectiveness in removing heat from the device. The additionofplatedthrough-holestoheat-dissipatinglayersalsoimprovestheheatsinkeffectiveness. Power dissipation depends on input voltage and load conditions. Power dissipation (P ) can be approximated by D the product of the output current times the voltage drop across the output pass element (V to V ), as shown IN OUT inEquation4. 3 (cid:11)9 – 9 (cid:12)u, D IN OUT OUT (4) 18 SubmitDocumentationFeedback Copyright©2001–2015,TexasInstrumentsIncorporated ProductFolderLinks:TPS793

TPS793 www.ti.com SLVS348L–JULY2001–REVISEDMAY2015 Power Dissipation (continued) Power dissipation resulting from quiescent current is negligible. Excessive power dissipation triggers the thermal protectioncircuit. Figure 30 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) Figure30.
