LM2931ASX-5.0 TI LDO Regulator | TO-263 (DDPAK-3) | 5.0V Output, 100mA

Product Overview

The LM2931ASX-5.0 is a low dropout voltage regulator from Texas Instruments (TI), offering a fixed 5.0V output with a maximum output current of 100mA. Housed in the TO-263 (DDPAK-3) package, this device is designed for applications requiring low quiescent current and high input voltage tolerance up to 26V. Its low dropout voltage of typically 0.6V at full load ensures efficient regulation even when the input voltage is close to the output. The LM2931ASX-5.0 features built-in protection against reverse battery, short circuit, and overtemperature, making it a robust choice for automotive and industrial systems.
