    8MHz PWM Synchronous Buck Regulator
    with LDO Standby Mode General Description Features The Micrel MIC2285A is a high efficiency 8MHz
    PWM synchronous buck (step-down) regulator that
    features a LOWQВ® LDO standby mode that draws
    only 20ВµA of quiescent current. The MIC2285A
    allows an ultra-low noise, small size, and high
    efficiency solution for portable power applications.
    In PWM mode, the MIC2285A operates with a
    constant frequency 8MHz PWM control. Under light
    load conditions, such as in system sleep or standby
    modes, the PWM switching operation can be
    disabled to reduce switching losses. In this light load
    LOWQВ® mode, the LDO maintains the output voltage
    and draws only 18ВµA of quiescent current. The LDO
    mode of operation saves battery life while not
    introducing spurious noise and high ripple as
    experienced with pulse skipping or bursting mode
    regulators.
    The MIC2285A operates from 2.7V to 5.5V input and
    features internal power MOSFETs that can supply
    up to 600mA output current in PWM mode. It can
    operate with a maximum duty cycle of 100% for use ...
