LP3963ESX-2.5/NOPB TI LDO Voltage Regulator | TO-263 (DDPAK-5) | 2.5V Output, 3A

Product Overview

The LP3963ESX-2.5/NOPB is a high-performance low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed 2.5V output with a maximum current of 3A. 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 dropout voltage as low as 240mV at full load, it ensures efficient operation even when the input voltage is close to the output. The LP3963 series features fast transient response, low output noise, and built-in protection circuits including overcurrent and thermal shutdown.
