MIC5239
Low Quiescent Current 500mA μCap
LDO Regulator
General Description
Features
The MIC5239 is a low quiescent current, μCap low-dropout
regulator. With a maximum operating input voltage of 30V
and a quiescent current of 23μA, it is ideal for supplying
keep-alive 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 μCap LDO, the MIC5239 is stable with either a
ceramic or a tantalum output capacitor. It only requires a
3.3μF 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, overvolt-
age shutdown, reverse-leakage protection, and reverse-
battery protection.
