Description

The MIC5236 is a low quiescent current,  µ Cap low-dropout regulator. With a maximum operating input voltage of 30V and a quiescent current of 20 µ A, it is ideal for supplying keep- alive power in systems with high-voltage batteries. Capable of 150mA output, the MIC5236 has a dropout voltage of only 300mV. It can also survive an input transient of 20V to +60V.

As a  µ Cap LDO, the MIC5236 is stable with either a ceramic or a tantalum output capacitor. It only requires a 1.0 µ F output capacitor for stability. The MIC5236 includes a logic compatible enable input and an undervoltage error flag indicator. Other features of the MIC5236 include thermal shutdown, current-limit, overvoltage shutdown, load-dump protection, reverse leakage protections, and reverse battery protection.

Available in the thermally enhanced SOP-8 and MSOP-8, the MIC5236 comes in fixed 2.5V, 3.0V, 3.3V, 5.0V, and adjustable voltages. For other output voltages, contact Micrel.
