LP38859S-1.2/NOPB TI LDO Regulator | TO-263 (DDPAK-5) | 1.2V Fixed Output, 3A

Product Overview

The LP38859S-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 the TO-263 (DDPAK-5) package, this device offers excellent thermal performance and reliability for demanding applications. With a low dropout voltage of typically 310mV at full load, it ensures efficient power conversion even when the input voltage is close to the output. The LP38859S-1.2/NOPB features fast transient response, low output noise, and a wide input voltage range from 1.5V to 5.5V, making it ideal for powering sensitive analog and digital circuits.
