Description

The L4949ED-E and L4949EP-E are monolithic

integrated 5V voltage regulators with a very low

dropout output and additional functions as poweron reset and input voltage sense. They are

designed for supplying the microcomputer

controlled systems especially in automotive

applications.

Features

■ Automotive Grade: compliance with AEC

guidelines

■ Operating DC supply voltage range 5 V - 28 V

■ Transient supply voltage up to 40V

■ Extremely low quiescent current in standby

mode

■ High precision standby output voltage 5V±1

■ Output current capability up to 100mA

■ Very low dropout voltage less than 0.5V

■ Reset circuit sensing the output voltage

■ Programmable reset pulse delay with external

capacitor

■ Voltage sense comparator
