Product Introduction
The MIC5239 is a low quiescent current, µCap low-dropout regulator. With a maximum operating input voltage of 30V and a quiescent current of 23 µA, it is ideal for supplying keep-alive power in systems with high voltage batteries.
Capable of 500 mA output, the MIC5239 has a dropout voltage of only 350 mV. 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 3.3 µF 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, 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.
