REG103FA-2.5/500 TI LDO Regulator | TO-263 (DDPAK-5) | 2.5V Output, 500mA

Product Overview

The REG103FA-2.5/500 from Texas Instruments is a high-performance, low-dropout (LDO) voltage regulator designed to deliver a fixed output voltage of 2.5V with a maximum output current of 500mA. Housed in a TO-263 (DDPAK-5) package, this device offers excellent line and load regulation, making it ideal for noise-sensitive applications. Its low dropout voltage (typically 115mV at full load) ensures efficient operation even when the input voltage is close to the output. The REG103FA-2.5/500 also features a low quiescent current (1mA typical) and fast transient response, enhancing system reliability.
