  • 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.

    主要特性

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