Product Overview
The LP3856ESX-1.8/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments (TI). It delivers a fixed output voltage of 1.8V with a maximum output current of 3A. Housed in a TO-263 (DDPAK-5) package, this device is designed for applications requiring low noise, fast transient response, and high accuracy. The LP3856 family features a low dropout voltage of typically 0.38V at 3A, making it suitable for converting from 2.5V or 3.3V rails to 1.8V with high efficiency. It includes enable/shutdown control, overcurrent protection, and thermal shutdown.
