MIC5239  
Low Quiescent Current 500mA µCap  
LDO Regulator  
General Description  
Features  
The MIC5239 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.  
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  
Logic compatible enable input  
Low output voltage error flag indicator  
Overcurrent protection  
Capable of 500mA output, the MIC5239 has a dropout  
voltage of only 350mV. It can provide high output current  
for applications such as USB.  
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, overvolt-  
age shutdown, reverse-leakage protection, and reverse-  
battery protection.  
Thermal shutdown  
Reverse-leakage protection  
Reverse-battery protection  
High-power SOIC-8, MSOP-8 and SOT-223 packages  
Available in the thermally enhanced SOIC-8, MSOP-8 and  
SOT-223, the MIC5239 comes in fixed 1.5V, 1.8V, 2.5V,  
3.0V, 3.3V and 5.0V, and adjustable voltages. For other  
output voltages, contact Micrel.  
Applications  
USB power supply  
Keep-alive supply in notebook and portable personal  
computers
