... Capable of 150mA output, the MIC5236 has a dropout voltage of only 300mV. It can also survive an input transient of –20V to +60V Cap LDO, the MIC5236 is stable with either a ceramic or a tantalum output capacitor. It only requires a 1.0 F output capacitor for stability. The MIC5236 includes a logic compatible enable input and an undervoltage error flag indicator ...
