The MIC5239BMM-TR 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 MIC5239BMM-TR has a dropout voltage of only 350mV. It can provide high output current for applications such as USB.
As a µCap LDO, the MIC5239BMM-TR is stable with either a ceramic or a tantalum output capacitor. It only requires a 3.3µF output capacitor for stability.
The MIC5239BMM-TR includes a logic-compatible enable input and an undervoltage error flag indicator. Other features of the MIC5239BMM-TR 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 MIC5239BMM-TR comes in fixed 3.0V and adjustable voltages.
