LP38859SX-1.2/NOPB TI LDO Regulator | TO-263 (DDPAK-5) | 1.2V Fixed Output, 3A

Product Overview

The LP38859SX-1.2/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed 1.2V output with a maximum current of 3A. Housed in a TO-263 (DDPAK-5) package, this device offers excellent line and load regulation, making it ideal for power-sensitive applications. With a dropout voltage as low as 420mV at full load, it ensures efficient operation even with minimal input-to-output voltage differential. The LP38859SX-1.2/NOPB features enable/shutdown functionality, overcurrent protection, and thermal shutdown, providing robust performance in demanding environments.
