LP3891ES-1.5/NOPB TI LDO Regulator | TO-263 (DDPAK-5) | 1.5V Fixed Output, 1A

Product Overview

The LP3891ES-1.5/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments (TI). It provides a fixed output voltage of 1.5V with a maximum output current of 1A. Housed in a TO-263 (DDPAK-5) package, this device is designed for applications requiring low noise, fast transient response, and high accuracy. The LP3891 features a low dropout voltage of typically 0.38V at 1A load, making it ideal for post-regulation and battery-powered systems. Its enable pin allows for power sequencing and shutdown control, while the output voltage accuracy is ±1.5% over line, load, and temperature variations.
