Introduction

The TPS79530DCQ is a high-performance, low-dropout (LDO) linear voltage regulator that provides a fixed 3V output voltage. It is designed to deliver up to 500mA of output current while maintaining excellent power supply rejection ratio (PSRR) and low quiescent current. The device features protection circuitry including over-current, over-temperature, reverse polarity, and under-voltage lockout (UVLO) to ensure reliable and safe operation.
