MIC5236  
Low Quiescent Current µCap LDO Regulator  
Preliminary Information  
General Description  
Features  
The MIC5236 is a low quiescent current, µCap low-dropout  
regulator. With a maximum operating input voltage of 30V  
andaquiescentcurrentof20µA, itisidealforsupplyingkeep-  
alive power in systems with high-voltage batteries.  
Ultra-low quiescent current (I = 20µA @I = 100µA)  
Wide input range: 2.3V to 30V  
Q

Low dropout:  
230mV @50mA;  
300mV @150mA  
Fixed 2.5V, 3.0V, 3.3V, 5.0V, and Adjustable outputs  
±1.0% initial output accuracy  
Stable with ceramic or tantalum output capacitor  
Load dump protection: 20V to +60V input transient  
survivability  
Logic compatible enable input  
Low output flag indicator  
Overcurrent protection  
Thermal shutdown  
Reverse-leakage protection  
Capable of 150mA output, the MIC5236 has a dropout  
voltage of only 300mV. It can also survive an input transient  
of –20V to +60V.  
As a µCap LDO, the MIC5236 is stable with either a ceramic  
or a tantalum output capacitor. It only requires a 1.0µF output  
capacitor for stability.  
TheMIC5236includesalogiccompatibleenableinputandan  
undervoltage error flag indicator. Other features of the  
MIC5236 include thermal shutdown, current-limit, overvolt-  
age shutdown, load-dump protection, reverse leakage pro-  
tections, and reverse battery protection.  
Reverse-battery protection  
AvailableinthethermallyenhancedSOP-8andMSOP-8, the  
MIC5236 comes in fixed 2.5V, 3.0V, 3.3V, 5.0V, and adjust-  
able voltages. For other output voltages, contact Micrel.
