The MIC5239YMM 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 MIC5239YMM has a dropout voltage of only 350mV. It can provide high output current for applications such as USB.
As a µCap LDO, the MIC5239YMM is stable with either a ceramic or a tantalum output capacitor. It only requires a 3.3µF output capacitor for stability.
The MIC5239YMM includes a logic-compatible enable input and an undervoltage error flag indicator. Other features of the MIC5239YMM 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 packages, the MIC5239YMM comes in fixed 3.0V and adjustable voltages.
