MIC5238
Ultra-Low Quiescent Current, 150mA
μCap LDO Regulator
General Description
Features
The MIC5238 is an ultra-low voltage output, 150mA LDO
regulator. Designed to operate in a single supply or dual
supply mode, the MIC5238 consumes only 23μA of bias
current, improving efficiency. When operating in the dual
supply mode, the efficiency greatly improves as the higher
voltage supply is only required to supply the 23μA bias
current while the output and base drive comes off of the
much lower input supply voltage.
As a μCap regulator, the MIC5238 operates with a 2.2μF
ceramic capacitor on the output, offering a smaller overall
solution. It also incorporates a logic-level enable pin that
allows the MIC5238 to be put into a zero off-current mode
when disabled.
