General Description
The MIC5234 is a low-quiescent current, μCap low dropout regulator. With a maximum operating input voltage of 30V and quiescent current of 20μA, it is ideal for supplying keep-alive power in systems with high-voltage batteries.
Capable of 150mA output, the MIC5234 has a dropout voltage of only 320mV. It can also survive an input transient of –20V to +32V. The MIC5234 requires only a 2.2μF output capacitor for stable operation.

FEATUREs
• Ultra-low quiescent current (IQ = 20μA @ IO = 100μA)
• Wide input voltage range: 2.3V to 30V
• Low dropout:
    − 230mV @50mA
    − 320mV @150mA
• Adjustable output voltage
• Typical ±1.0% initial output accuracy
• Logic compatible enable input
• Overcurrent protection
• Thermal-shutdown protection
• Reverse-leakage and reverse-battery protection
• Thermally enhanced 8-pin ePad SOIC package

APPLICATIONs
• “Keep-alive” supply in notebook and portable personal computers
• Logic supply from high-voltage batteries
• Automotive electronics
• Battery-powered systems
