LP3855ES-2.5/NOPB TI LDO Regulator | TO-263 (DDPAK-5) | 2.5V Fixed Output, 1.5A

Product Overview

The LP3855ES-2.5/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments (TI). It provides a fixed 2.5V output with a maximum output current of 1.5A. Housed in a TO-263 (DDPAK-5) package, this device is designed for applications requiring low noise, fast transient response, and high accuracy. The LP3855 family features a low dropout voltage of typically 240mV at full load, making it ideal for post-regulation and battery-powered systems. With an enable pin and overcurrent/thermal protection, it offers reliable operation in demanding environments.
