MIC5271

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).

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 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 also includes a TTL-compatible enable pin, allowing the user to put the part into a zero-current off mode.

The MIC5271 is available in the 5-pin SOT-23 package for space saving applications and it is available with an adjustable output.
