REG103UA-A/2K5 TI LDO Regulator | 8-SOIC | 500mA, Low Dropout

Product Overview

The REG103UA-A/2K5 is a low-dropout (LDO) linear regulator from Texas Instruments, designed to deliver up to 500mA of output current with a dropout voltage of typically 115mV at full load. It operates over an input voltage range of 2.5V to 5.5V and provides a fixed output voltage of 3.3V with ±2% accuracy. The device features low quiescent current (typically 130µA) and fast transient response, making it suitable for battery-powered and noise-sensitive applications. Housed in an 8-pin SOIC package, it includes enable, bypass, and output voltage sense pins for flexible design.
