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.
