LP3891EMR-1.8/NOPB TI LDO Regulator | 8-SO-POWERPAD | 1.8V Fixed Output, 1A

Product Overview

The LP3891EMR-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 1A. Housed in an 8-SO-POWERPAD package, this device offers excellent thermal performance and is ideal for power-sensitive applications requiring low noise and high accuracy. The LP3891EMR-1.8/NOPB features a low dropout voltage of typically 120mV at full load, enabling efficient operation even with small input-to-output voltage differentials. Its wide input voltage range of 2.5V to 5.5V makes it suitable for a variety of power supply architectures.
