General Description

The MIC5270 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 MIC5270 sinks 100mA of output current at very low dropout voltage (600mV maxi mum at 100mA of output current).

Features

• Stable with ceramic or tantalum capacitor

• Low dropout voltage: 500mV @ 100mA

• Low ground current: 35µA @ load = 100µA

• Tight initial accuracy: ±2

• Tight load and line regulation

• Thermal shutdown

• Current limiting

• IttyBitty® SOT-23-5 packaging

Applications

• GaAsFET bias

• Portable cameras and video recorders

• PDAs

• Battery-powered equipment
