LP3881ESX-1.2/NOPB TI LDO Regulator | TO-263 (DDPAK-5) | 1.2V Fixed Output, 800mA

Product Overview

The LP3881ESX-1.2/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments (TI), designed to deliver a fixed 1.2V output with a maximum current of 800mA. Housed in a TO-263 (DDPAK-5) package, this device offers excellent line and load regulation, making it ideal for noise-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 LP3881ESX-1.2/NOPB features a wide input voltage range from 2.5V to 5.5V, enabling compatibility with various power sources. Its enable pin allows for power sequencing and shutdown control, reducing quiescent current to near zero when disabled. The device also includes current limit and thermal shutdown protection for robust operation.
