LM2940SX-5.0 TI LDO Regulator | TO-263 (DDPAK-3) | 5.0V Fixed Output, 1A

Product Overview

The LM2940SX-5.0 from Texas Instruments is a low dropout (LDO) voltage regulator designed to deliver a fixed 5.0V output with a maximum current of 1A. Housed in the TO-263 (DDPAK-3) package, this device offers excellent line and load regulation, making it suitable for a wide range of applications. The LM2940SX-5.0 features a dropout voltage of typically 0.5V at full load, ensuring efficient operation even when the input voltage is close to the output. It includes internal protection circuits such as current limiting and thermal shutdown, enhancing system reliability.
