GENERAL DESCRIPTION
FEATURES
Capable of 500mA output, the MIC5239 has a dropout voltage of only 350mV.● Ultra-low quiescent current (IQ = 23µA @IO = 100µA)
● Continuous 500mA output current
● Wide input range: 2.3V to 30V
● Low dropout voltage: 350mV @500mA
● ±1.0% initial output accuracy
● Stable with ceramic or tantalum output capacitor 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, overvoltage shutdown, reverse-leakage protection, and reversebattery protection.
