LP38843SX-1.2 TI LDO Regulator | DDPAK/TO-263-5 | 1.2V Fixed Output, 3A

Product Overview

The LP38843SX-1.2 is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments (TI). It delivers a fixed output voltage of 1.2V with a maximum output current of 3A. Housed in a DDPAK/TO-263-5 package, this device is designed for applications requiring tight voltage regulation, low noise, and high efficiency. The LP38843SX-1.2 features a low dropout voltage of typically 420mV at full load, making it ideal for converting from 1.5V or 1.8V rails. It also offers excellent transient response and stability with low-ESR ceramic output capacitors.
