TPS7A91 - LDO Voltage Regulator

General Description

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.

Key Features

  • 1 1.0% Accuracy Over Line, Load, and Temperature.
  • Low Output Noise: 4.7 µVRMS (10 Hz.
