LP3891ESX-1.2/NOPB TI Voltage Regulator | TO-263 (DDPAK-5) | 1.2V Fixed Output, 1A

Product Overview

The LP3891ESX-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 1A. 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 120mV at full load, it ensures efficient operation even when the input voltage is close to the output. The LP3891 features fast transient response, low output noise, and a wide input voltage range from 2.5V to 5.5V, making it ideal for powering sensitive analog and digital circuits.
