    MP20045DQ-LF-Z

    The MP20045 is a low-dropout linear regulator
    supplies up to 1A current with 140mV dropout
    voltage. The output voltage is set externally
    which ranges from 1.5V to 5V by operating from
    +2.5V to +5.5V input or can be preset internally
    from 1.5V to 5V.
    An internal PMOS pass element is used to
    allow a low 110μA ground current, making the
    MP20045 suitable for battery-power devices.
    Other features include low-power shutdown,
    short-circuit and thermal protection. The
    MP20045 is available in 8-pin QFN (3mm x
    3mm) and SOIC8E packages.
