MIC5239

Low Quiescent Current 500mA µCap

LDO Regulator

General Description

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.

Available in the thermally enhanced SOIC-8, MSOP-8 and

SOT-223, the MIC5239 comes in fixed 1.5V, 1.8V, 2.5V,

3.0V, 3.3V and 5.0V, and adjustable voltages. For other

output voltages, contact Micrel.
