REG103FA-AKTTT TI LDO Regulator | TO-263 (DDPAK-5) | 500mA, 1.8V-5.5V

Product Overview

The REG103FA-AKTTT 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 a TO-263 (DDPAK-5) package, this device delivers up to 500mA of output current with a dropout voltage as low as 115mV at full load. The input voltage range is from 1.8V to 5.5V, making it suitable for battery-powered and low-voltage systems. The REG103FA-AKTTT features a fixed output voltage of 3.3V (or other options), with an initial accuracy of ±1.5% and excellent line and load regulation. It includes built-in protection features such as overcurrent and thermal shutdown, ensuring reliable operation in demanding environments.
