Overview
MIC5238 Ultra-Low Quiescent Current, 150mA µCap LDO Regulator General Description 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 MIC...
