MIC5270 Micrel MIC5270 µCap Negative Low-Dropout Regulator Final Information General Description Features The MIC5270 is a µCap 100mA negative regulator in a SOT- • Stable with ceramic or tantalum capacitor 23-5 package. With better than 2% initial accuracy, this • Low dropout voltage: 500mV @ 100mA regulator provides a very accurate supply voltage for applica- • Low ground current: 35µA @ load = 100µA tions that require a negative rail. The MIC5270 sinks 100mA • Tight initial accuracy: ±2% of output current at very low dropout voltage (600mV maxi- • Tight load and line regulation mum at 100mA of output current). • Thermal shutdown • Current limiting The µCap regulator design is optimized to work with low- • IttyBitty™ SOT-23-5 packaging value, low-cost ceramic capacitors.
