MIC5225
Ultra-Low Quiescent Current
150mA µCap Low Dropout Regulator
General Description
The MIC5225 is a 150mA highly accurate, low dropout
regulator with high input voltage and ultra-low ground
current. This combination of high voltage and low ground
current makes the MIC5225 ideal for a wide variety of
applications including USB and portable electronics
applications, using 1-cell, 2-cell or 3-cell Li-Ion battery
inputs.
A µCap LDO design, the MIC5225 is stable with either a
ceramic or tantalum output capacitor. It only requires a
2.2µF capacitor for stability.
Features of the MIC5225 includes enable input, thermal
shutdown, current limit, reverse battery protection, and
reverse leakage protection.
Available in fixed and adjustable output voltage versions,
the MIC5225 is offered in the IttyBitty
®
SOT23-5 package
with a junction temperature range of –40°C to +125°C.
Data sheets and support documentation can be found on
Micrel’s web site at www.micrel.com.
Features
Wide input voltage range: 2.3V to 16V
High output accuracy of ±2.0% over temperature
Guaranteed 150mA output
Very low ground current: 29µA
Low dropout voltage of 310mV at 150mA
µCap: Stable with ceramic or tantalum capacitors
Excellent line and load regulation specifications
Reverse battery protection
Reverse leakage protection
Zero shutdown current
Thermal shutdown and current limit protection
