Description

The MIC5239 is a low quiescent current, Cap low-dropout regulator. With a maximum operating input voltage of 30V
and a quiescent current of 23A, it is ideal for supplying keepalive power in systems with high-voltage batteries.

Capable of 500mA output, the MIC5239 has a dropout voltage of only 350mV. It can provide high output current for
applications such as USB.

As a Cap LDO, the MIC5239 is stable with either a ceramic or a tantalum output capacitor. It only requires a 3.3F output capacitor for stability.

The MIC5239 includes a logic compatible enable input and an undervoltage error flag indicator. Other features of the
MIC5239 include thermal shutdown, current-limit, overvoltage shutdown, load-dump protection, reverse leakage protections,and reverse battery protection.

Available in the thermally enhanced SOIC-8, MSOP-8 and SOT-223, the MIC5239 comes in fixed 3.0V and adjustable
voltages. For other output voltages, contact Micrel.
