LP3871EMP-1.8/NOPB TI LDO Regulator | SOT-223-5 | 800mA, 1.8V Output

Product Overview

The LP3871EMP-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 compact SOT-223-5 package, this device offers excellent line and load regulation, making it ideal for noise-sensitive applications. The LP3871 features a low dropout voltage of typically 240mV at full load, enabling efficient operation even when the input voltage is close to the output. With an enable pin for power sequencing and thermal shutdown protection, it ensures reliable performance in demanding environments.
