Introduction

The TPS79401 is a low-dropout (LDO) linear voltage regulator that provides a regulated positive output voltage from a higher input voltage. It features a very low quiescent current and high power supply rejection ratio (PSRR) across a wide frequency range. The device is optimized for battery-powered applications and other space-constrained designs that require a small footprint and low power consumption.
