... Capable of 500mA output, the MIC5239 has a dropout voltage of only 350mV. It can provide high output current for applications such as USB µCap LDO, the MIC5239 is stable with either a ceramic or a tantalum output capacitor. It only requires a 3.3µF output capacitor for stability. The MIC5239 includes a logic compatible enable input and an undervoltage error flag indicator ...

... Micrel Application Information The MIC5239 provides all of the advantages of the MIC2950: wide input voltage range, and reversed- battery protection, with the added advantages of reduced quiescent current and smaller package. Additionally, when disabled, quiescent current is reduced to 0.1µA. Enable A low on the enable pin disables the part, forcing the quiescent current to less than 0.1µ ...
