LP3855ES-1.8/NOPB TI LDO Regulator | TO-263 (DDPAK-5) | 1.8V Fixed Output, 1.5A

Product Overview

The LP3855ES-1.8/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments (TI). It delivers a fixed output voltage of 1.8V 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 LP3855ES-1.8/NOPB features a dropout voltage of typically 310mV at full load, making it suitable for systems with tight voltage margins. It also includes enable/shutdown functionality, overcurrent protection, and thermal shutdown for robust operation.
