... This combination of high voltage and low ground current makes the MIC5233 ideal for multi-cell Li-Ion battery systems. A µCap LDO design, the MIC5233 is stable with either ceramic or tantalum output capacitor. It only requires a 2.2µF capacitor for stability. Features of the MIC5233 include enable input, thermal shut- down, current limit, reverse battery protection, and reverse leakage protection ...

... Forcing the enable pin high enables the output voltage. Input Capacitor The MIC5233 has high input voltage capability up to 36V. The input capacitor must be rated to sustain voltages that may be used on the input. An input capacitor may be required when the device is not near the source power supply or when supplied by a battery ...
