LP3965ESX-3.3/NOPB TI LDO Regulator | TO-263 (DDPAK-5) | 3.3V Output, 1.5A

Product Overview

The LP3965ESX-3.3/NOPB is a high-performance low-dropout (LDO) voltage regulator from Texas Instruments (TI), designed to deliver a fixed 3.3V 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 suitable for noise-sensitive applications. With a dropout voltage as low as 380mV at full load, it ensures efficient operation even when the input voltage is close to the output. The LP3965ESX-3.3/NOPB features a wide input voltage range from 2.5V to 7V, enabling use in various power supply designs. Its enable pin allows for power sequencing, and the built-in overcurrent and thermal shutdown protections enhance system reliability.
