TPS780 www.ti.com SBVS083E–JANUARY2007–REVISEDJANUARY2015 7 Detailed Description 7.1 Overview The TPS780 family of low-dropout regulators (LDOs) is designed specifically for battery-powered applications where ultralow quiescent current is a critical parameter. The absence of pulldown circuitry at the output of the LDO provides the flexibility to use the regulator output capacitor as a temporary backup power supply for a short period of time (for example, during battery replacement). The TPS780 family is compatible with the TI MSP430 and other similar products. The enable pin (EN) is compatible with standard CMOS logic. This LDO family is stablewithanyoutputcapacitorgreaterthan1.0µF. 7.2 Functional Block Diagram IN OUT Current Limit Thermal Shutdown X EPROM U M EN Bandgap Active Pull- 10kW (1) Down V /FB SET LOGIC GND (1) Feedbackpin(FB)foradjustableversions;V forfixedvoltageversions.

During current limit, the output sources a fixed amount of current that is largely independent of output voltage.

The PMOS pass element in the TPS780 family has a built-in body diode that conducts current when the voltage at OUT exceeds the voltage at IN.

This capacitor counteracts reactive input sources and improves transient response, noise rejection, and ripple rejection. A higher-value capacitor may be necessary if large, fast rise-time load transients are anticipated, or if the device is not located near the power source. If source impedance is not sufficiently low, a 0.1-μF input capacitormaybenecessarytoensurestability. The TPS780 family is designed to be stable with standard ceramic capacitors with values of 1.0 μF or larger at the output. X5R- and X7R-type capacitors are best because they have minimal variation in value and ESR over temperature. Maximum ESR should be less than 1.0 Ω. With tolerance and dc bias effects, the minimum capacitancetoensurestabilityis1μF. 18 SubmitDocumentationFeedback Copyright©2007–2015,TexasInstrumentsIncorporated ProductFolderLinks:TPS780

TPS780 www.ti.com SBVS083E–JANUARY2007–REVISEDJANUARY2015 8.2.2.2 DropoutVoltage The TPS780 family uses a PMOS pass transistor to achieve low dropout. When (V – V ) is less than the IN OUT dropout voltage (V ), the PMOS pass device is the linear region of operation and the input-to-output resistance DO is the R of the PMOS pass element. V approximately scales with output current because the PMOS DS(on) DO device behaves like a resistor in dropout. As with any linear regulator, PSRR and transient response are degraded as (V – V ) approaches dropout. This effect is shown in Typical Characteristics. Refer to IN OUT applicationreportSLVA207,UnderstandingLDODropout,availablefromwww.ti.com. 8.2.2.3 TransientResponse As with any regulator, increasing the size of the output capacitor reduces overshoot and undershoot magnitude butincreasesdurationofthetransientresponse.Formoreinformation,seeFigure48. 8.2.2.4 MinimumLoad The TPS780 family is stable with no output load. Traditional PMOS LDO regulators suffer from lower loop gain at very light output loads. The TPS780 employs an innovative, low-current circuit under very light or no-load conditions, resulting in improved output voltage regulation performance down to zero output current.

The TPS780 family offers many output voltage versions to allow designers to optimize the supply voltage for the processing speed required of the MSP430. This flexible architecture minimizes the supply current consumed by the particular MSP430 application. The MSP430 total system power can be reduced by substituting the 500-nA I TPS780seriesLDOinplaceofanexistingultralowI LDO(typicalbestcase=1μA).Additionally,DVSallows Q Q forincreasingtheclockspeedinactivemode(MSP430V =3.6V).The3.6-VV reducestheMSP430timein CC CC active mode. In low-power mode, MSP430 system power can be further reduced by lowering the MSP430 V to CC 2.2Vinsleepmode. Key features of the TPS780 series are an ultralow quiescent current (500 nA), DVS, and miniaturized packaging. The TPS780 family are available in SON-6 and TSOT-23 packages. Figure 59 shows a typical MSP430 circuit powered by an LDO without DVS. Figure 60 is an MSP430 circuit using a TPS780 LDO that incorporates an integrated DVS, thus simplifying the circuit design. In a circuit without DVS, as Figure 59 illustrates, V is CC always at 3.0 V. When the MSP430 goes into sleep mode, V remains at 3.0 V; if DVS is applied, V could be CC CC reducedinsleepmode.InFigure60,theTPS780LDOwithintegratedDVSmaintains3.6-VV untilalogichigh CC signal from the MSP430 forces V to level shift V from 3.6 V down to 2.2 V, thus reducing power in sleep OUT OUT mode. 20 SubmitDocumentationFeedback Copyright©2007–2015,TexasInstrumentsIncorporated ProductFolderLinks:TPS780

TPS780WithIntegratedDVS The other benefit of DVS is that it allows a higher V voltage on the MSP430, increasing the clock speed and CC reducingtheactivemodedwelltime. The total system power savings is outlined in Table 5, Table 6, and Table 7. In Table 5, the MSP430 power savings are calculated for various MSP430 devices using a TPS780 series with integrated DVS versus a standard ultralow IQ LDO without DVS. In Table 6, the TPS780 series quiescent power is calculated for a VIN of 4.2V,withthesameVINusedfortheultralowIQLDO.QuiescentpowerdissipationinanLDOistheVINvoltage times the ground current, because zero load is applied. After the dissipation power is calculated for the individual LDOs in Table 6, simple subtraction outputs the LDO power savings using the TPS780 series. Table 7 calculates the total system power savings using a TPS780 series LDO in place of an ultralow IQ 1.2-μA LDO in an MSP430F1121 application. There are many different versions of the MSP430. Actual power savings vary dependingontheselecteddevice. Copyright©2007–2015,TexasInstrumentsIncorporated SubmitDocumentationFeedback 21 ProductFolderLinks:TPS780

TPS780xxDDCPackageLayoutExample 10.3 Thermal Considerations Thermal protection disables the device output when the junction temperature rises to approximately 160°C, allowing the device to cool. After the junction temperature cools to approximately 140°C, the output circuitry is enabled. Depending on power dissipation, thermal resistance, and ambient temperature, the thermal protection circuit may cycle on and off again. This cycling limits the dissipation of the regulator, protecting it from damage asaresultofoverheating. Any tendency to activate the thermal protection circuit indicates excessive power dissipation or an inadequate heatsink. For reliable operation, limit junction temperature to 105°C maximum. To estimate the margin of safety in a complete design (including heatsink), increase the ambient temperature until the thermal protection is triggered;useworst-caseloadsandsignalconditions. The internal protection circuitry of the TPS780 family is designed to protect against overload conditions. However, this circuitry is not intended to replace proper heatsinking. Continuously running the TPS780 series intothermalshutdowndegradesdevicereliability. 10.4 Power Dissipation The ability to remove heat from the die is different for each package type, presenting different considerations in the PCB layout. The PCB area around the device that is free of other components moves the heat from the devicetotheambientair.PerformancedataforJEDEClow-andhigh-KboardsaregiveninThermalInformation. Using heavier copper increases the effectiveness in removing heat from the device. The addition of plated through-holes to heat-dissipating layers also improves the heatsink effectiveness.
