    Ultra low drop-low noise BiCMOS voltage regulators low ESR capacitors compatible

    Parameters
    Operating RangeAutomotive
    Operating Temp Min Celsius-40.0
    Operating Temp Max Celsius125.0
    ECCN USEAR99
    ECCN EUNEC
    Packing TypeTape And Reel
    RoHs compliantEcopack2
    GradeIndustrial
    Package NameSOT23-5L
    Description

    The LD3985 provides up to 150 mA, from 2.5 V to 6 V input voltage. The ultra low drop voltage, low quiescent current and low noise make it suitable for low power applications and in battery-powered systems. Regulator ground current increases slightly in dropout only, prolonging the battery life....
