Micrel
General Description
The MIC5236 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 has a dropout voltage of only 300mV. It can also survive an input transient of –20V to +60V.
FEATUREs
• Ultra-low quiescent current (IQ = 20µA @IO = 100µA)
• Wide input range: 2.3V to 30V
• 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
• Reverse-battery protection
• High-power SOIC-8 and MSOP-8
APPLICATIONs
• Keep-alive supply in notebook and portable personal computers
• Logic supply from high-voltage batteries
• Automotive electronics
• Battery-powered systems
