LP3871ESX-1.8/NOPB TI LDO Regulator | TO-263 (DDPAK-5) | 1.8V Fixed Output, 800mA

Product Overview

The LP3871ESX-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 typically 240mV at full load, it ensures efficient operation even with low input-to-output voltage differentials. The LP3871 features a low quiescent current of 30µA (typical) and includes enable/shutdown functionality, output current limit, and thermal shutdown protection.
