    2MHz PWM Synchronous Buck
    Regulator with LDO Standby Mode General Description Features The Micrel MIC2205 is a high efficiency 2MHz PWM
    synchronous buck (step-down) regulator that
    features a LOWQ™ LDO standby mode that draws
    only 18µA of quiescent current. The MIC2205
    allows an ultra-low noise, small size, and high
    efficiency solution for portable power applications.
    In PWM mode, the MIC2205 operates with a
    constant frequency 2MHz 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 LOWQ™ mode, the LDO maintains the output
    voltage and draws only 18µA 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 MIC2205 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 ...
