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
• Positive and negative enable thresholds
• Low dropout voltage: -500mV @ -100mA
• Low ground current: -25µA @ load = -100µA
• Tight initial accuracy: ±2%
• Tight load and line regulation
• Thermal shutdown and Current limit protection
• IttyBitty 5-pin SOT-23 packaging
• Zero-current off mode
APPLICATIONs
• GaAsFET bias
• Portable cameras and video recorders
• PDAs
• Battery-powered equipment
• Post-regulation of DC-DC converters
