    MIC4575
    200kHz Simple 1A Buck Regulator General Description Features The MIC4575 is a series of easy to use fixed and
    adjustable BiCMOS step-down (buck) switch-mode voltage
    regulators. The 200kHz MIC4575 duplicates the pinout
    and function of the 52kHz LM2575. The higher switching
    frequency may allow up to a 2:1 reduction in output filter
    inductor size.
    The MIC4575 is available in 3.3V, and 5V fixed output
    versions or a 1.23V to 20V adjustable output version. Both
    versions are capable of driving a 1A load with excellent
    line and load regulation.
    The feedback voltage is guaranteed to В±2% tolerance for
    adjustable versions, and the output voltage is guaranteed
    to В±3% for fixed versions, within specified voltages and
    load conditions. The oscillator frequency is guaranteed to
    В±10%.
    In shutdown mode, the regulator draws less than 200ВµA
    standby current. The regulator performs cycle-by-cycle
    current limiting and thermal shutdown for protection under
    fault conditions.
    This series of simple switch-mode regulators requires a
    minimum number of external components and can operate
    using a standard series of inductors. Frequency compensation is provided internally. ...
