Product overview

Description

The L4949ED-E and L4949EP-E are monolithic

integrated 5V voltage regulators with a very low

dropout output and additional functions as power- on reset and input voltage sense. They are

designed for supplying the microcomputer

controlled systems especially in automotive applications.

  • All features

    • AEC-Q100 qualified
    • ECOPACK®: lead free and RoHS compliant
    • Operating DC supply voltage range 5 V - 28 V
    • Transient supply voltage up to 40 V
    • Extremely low quiescent current in standby
    • High precision standby output voltage 5V±1%
    • Output current capability up to 100 mA
    • Very low dropout voltage less than 0.5 V
    • Reset circuit sensing the output voltage
    • Programmable reset pulse delay with external capacitor
    • Voltage sense comparator
    • Thermal shutdown and short circuit protections
