General Description

The MIC5236 is a low quiescent current, µCap low-dropout

regulator. With a maximum operating input voltage of 30V and

a quiescent current of 20µA, it is ideal for supplying keep-alive

power in systems with high-voltage batteries.

Capable of 150mA output, the MIC5236 has a dropout volt-

age of only 300mV. It can also survive an input transient of

–20V to +60V.

As a µCap LDO, the MIC5236 is stable with either a ceramic

or a tantalum output capacitor. It only requires a 1.0µF 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 SOIC-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.
