L4940V5 General Description

The L4940V5 is a low-dropout voltage regulator IC that can provide a fixed output voltage of 5V with a maximum output current of 1.5A. It is designed to work with input voltages ranging from 6V to 26V, making it suitable for a wide range of applications.This regulator features a very low dropout voltage of only 1.1V at full load, which means it can regulate the output voltage even when the input voltage is very close to the desired output voltage. It also has a very low quiescent current of only 100µA, which helps to conserve power in battery-powered applications.The L4940V5 comes in a TO-220 package with thermal shutdown and short-circuit protection features to ensure safe operation. It is commonly used in embedded systems, automotive electronics, and power supply applications where a stable and reliable 5V source is required.
