General Description
The MIC5271 is a µCap 100 mA negative regulator in a SOT23-5 package. With better than 2% initial accuracy, this regulator provides a very accurate supply voltage for applications that require a negative rail. The MIC5271 sinks 100 mA of output current at very low dropout voltage (500 mV typical, 700 mV maximum at 100 mA of output current).
