General Description

The MIC5271 is a µCap 100mA negative regulator in a SOT-23-5 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 100mA of output current at very low dropout voltage (600mV maximum at 100mA of output current).

Features

• Stable with ceramic or tantalum capacitor
