4.Description
The TPS7A88-Q1is a dual,low-noise(4 μVRMS), low-dropout(LDO)voltageregulatorcapableof sourcing1 A per channelwith 250 mV of maximumdropout
TheTPS7A88-Q1providesthe flexibilityof twoindependentLDOsandapproximately50%smallersolutionsizethantwo single-channelLDOs.Eachoutputis adjustablewith externalresistorsfrom0.8 Vto 5.15V. The TPS7A88-Q1wideinput-voltagerangesupportsoperationas low as 1.4 V and up to 6.5 V.
With1% outputvoltageaccuracy(overline, load,andtemperature)and soft-startcapabilitiesto reducein-rushcurrent,the TPS7A88-Q1is idealfor poweringsensitiveanaloglow-voltagedevices(suchasvoltage-controlledoscillators[VCOs],analog-to-digitalconverters[ADCs],digital-to-analogconverters[DACs],high-endprocessors,and field-programmablegatearrays[FPGAs])
TheTPS7A88-Q1is designedto powernoise-sensitivecomponentssuchas thosefoundin RF,radarcommunications,andtelematicapplications.The low 4-μVRMSoutputnoiseand widebandPSRR(40 dB at 1 MHz)minimizesphasenoiseand clockjitter.Thesefeaturesmaximizeperformanceofclockingdevices,ADCs,and DACs.The TPS7A88-Q1featureswettableflanksfor simpleopticalinspection
