Product Introduction

Overview

The TPS7A7100 is a 1-A, fast-transient, low-dropout voltage regulator designed by Texas Instruments. This device is optimized for applications requiring very low dropout voltage and high accuracy over a wide range of operating conditions. The TPS7A7100 features an innovative user-configurable output voltage setting, eliminating the need for external resistors and associated errors. It offers a dropout voltage of 140 mV at 1 A, making it suitable for point-of-load (POL) applications. The regulator is stable with ceramic output capacitors and provides excellent line and load transient response.
