The MIC5270 is a Cap 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 maximum at 100mA of output current). The Cap regulator design is optimized to work with lowvalue, low-cost ceramic capacitors. The output typically requires only a 1F capacitance for stability. Designed for applications where small packaging and efficiency are critical, the MIC5270 combines LDO design expertise with IttyBitty packaging to improve performance and reduce power dissipation. Ground current is optimized to help improve battery life in portable applications. The MIC5270 is available in the SOT-23-5 package for space saving applications and it is available with fixed 3.0V, 4.1V, 5.0V, and adjustable outputs.
