The MIC5236-1.8BM is a low quiescent current, µCap low dropout regulator. With a maximum operating input voltage of 30V and a quiescent current of 20µA, it is ideal for supplying keep-alive power in systems with high-voltage batteries.
Capable of 150mA output, the MIC5236-1.8BM has a dropout voltage of only 300mV. It can also survive an input transient of -20V to +60V.
As a µCap LDO, the MIC5236-1.8BM is stable with either a ceramic or a tantalum output capacitor. It only requires a 1.0µF output capacitor for stability.
The MIC5236-1.8BM includes a logic-compatible enable input and an undervoltage error flag indicator. Other features of the MIC5236-1.8BM include thermal shutdown, current-limit, overvoltage shutdown, load-dump protection, reverse leakage protection, and reverse battery protection.
Available in the thermally enhanced SOIC-8 and MSOP-8 packages, the MIC5236-1.8BM comes in fixed 2.5V, 3.0V, 3.3V, 5.0V, and adjustable voltages.
