LP3883ES-1.2 TI LDO Regulator | TO-263 (DDPAK-5) | 3A Output, 1.2V Fixed

Product Overview

The LP3883ES-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 output current of 3A. Housed in the TO-263 (DDPAK-5) package, this device offers excellent thermal performance and is ideal for applications requiring a stable and efficient power supply. With a low dropout voltage of typically 340mV at full load, the LP3883ES-1.2 ensures high efficiency even when the input voltage is close to the output voltage. The device features a fast transient response, making it suitable for powering sensitive loads such as FPGAs, DSPs, and microprocessors.
