LP38855S-1.2 TI LDO Regulator | TO-263 (DDPAK-5) | 1.2V Output, 1.5A

Product Overview

The LP38855S-1.2 is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed 1.2V output with a maximum current of 1.5A. Housed in a TO-263 (DDPAK-5) package, this device offers excellent line and load regulation, making it ideal for power-sensitive applications. With a low dropout voltage of typically 120mV at full load, it ensures efficient operation even when the input voltage is close to the output. The LP38855S-1.2 features enable pin for power sequencing and includes overcurrent and thermal protection.
