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 maximum at 100mA of output current).
The µCap regulator design is optimized to work with low-value, low-cost ceramic capacitors. The output typically requires only a 1µF 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 output packages. For higher power requirements, see the MIC5209 or MIC5237.
Additional Features

Low dropout voltage: 500mV at 100mA
Low ground current: 35µA at load equals 100µA
Tight initial accuracy: ±2%
Tight load and line regulation
Thermal shutdown
Current limiting
