LM2940CSX-15/NOPB TI LDO Regulator | TO-263 (DDPAK-3) | 15V Output, 1A

Product Overview

The LM2940CSX-15/NOPB is a fixed-output low-dropout (LDO) voltage regulator from Texas Instruments, offering a stable 15V output with a maximum current of 1A. Housed in a TO-263 (DDPAK-3) package, this device is designed for applications requiring low dropout voltage and high accuracy. With a dropout voltage of typically 0.5V at full load, it ensures efficient operation even when the input voltage is close to the output. The LM2940 series features reverse battery protection, current limiting, and thermal shutdown, making it a robust choice for automotive, industrial, and telecommunications systems.
