TPS7A91 Datasheet - Texas Instruments

TPS7A91 LDO Voltage Regulator

The TPS7A91 is a low-noise (4.7 µVRMS), low-dropout (LDO) voltage regulator capable of sourcing 1 A with only 200 mV of maximum dropout. The TPS7A91 output is adjustable with external resistors from 0.8 V to 5.2 V. The TPS7A91 wide input-voltage range supports operation as low as 1.4 V and up to 6.5.
