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.
