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

Product Overview

The REG103UA-A from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator designed for applications requiring low noise, fast transient response, and high accuracy. Housed in an 8-pin SOIC package, this device delivers up to 500mA of output current with a dropout voltage as low as 115mV at full load. The REG103UA-A features a wide input voltage range from 2.5V to 5.5V, making it suitable for battery-powered and industrial systems. Its low quiescent current (1µA typical in shutdown) and excellent line/load regulation ensure stable operation across varying conditions.
