The MIC5271-3.0BM5 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 MIC5271-3.0BM5 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 MIC5271-3.0BM5 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 MIC5271-3.0BM5 also includes a TTL-compatible enable pin, allowing the user to put the part into a zero-current off mode.
The MIC5271-3.0BM5 is available in the 5-pin SOT-23 package for space saving applications and it is available with an adjustable output.
