LP3871ES-1.8/NOPB TI LDO Regulator | TO-263 (DDPAK-5) | 1.8V Fixed Output, 800mA

Product Overview

The LP3871ES-1.8/NOPB is a high-performance low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed 1.8V output with a maximum current of 800mA. Housed in a TO-263 (DDPAK-5) package, this device offers excellent line and load regulation, making it ideal for noise-sensitive applications. With a dropout voltage of only 240mV at full load, it ensures efficient operation even when the input voltage is close to the output. The LP3871ES-1.8/NOPB features enable/shutdown control, overcurrent protection, and thermal shutdown, providing robust performance in demanding environments.
