    8MHz Inductorless Buck Regulator
    with LDO Standby Mode General Description
    The Micrel MIC3385 is a high-efficiency inductorless buck
    В®
    regulator that features a LOWQ LDO standby mode that
    draws only 18ВµA of quiescent current. The MIC3385
    requires no external inductor enabling an ultra-low noise,
    small size, and high efficiency solution for portable power
    applications.
    In PWM mode, the MIC3385 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
    В®
    losses. In this light load LOWQ 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 MIC3385 operates from 2.7V to 5.5V input and
    features internal power MOSFETs that can supply up to ...
