    28mΩ RDSON 3A High Side Load Switch
    in 1.2mm x 1.2mm MLFВ® package General Description Features The MIC94040/1/2/3 is a family of high-side load switches
    designed to operate from 1.7V to 5.5V input voltage. The load
    switch pass element is an internal 28mΩ RDSON P-channel
    MOSFET which enables the device to support up to 3A of
    continuous current. Additionally, the load switch supports 1.5V
    logic level control and shutdown features in a tiny 1.2mm x
    1.2mm 4 pin MLF package.
    The MIC94040 and MIC94041 feature rapid turn on, while the
    MIC94042 and MIC94043 provide a slew rate controlled softstart turn-on of 100Вµs. The soft-start feature is provided to
    prevent an in-rush current event from pulling down the input
    supply voltage.
    The MIC94041 and MIC94043 feature an active load
    discharge circuit which switches in a 200Ω load when the
    switch is disabled to automatically discharge a capacitive load.
    An active pull-down on the enable input keeps the
    MIC94040/1/2/3 in a default OFF state until the enable pin is
    pulled above 1.2V. Internal level shift circuitry allows low
    voltage logic signals to switch higher supply voltages. The
    enable voltage can be as high as 5.5V and is not limited by
    the input voltage. ...
