MIC2211-GSYML-TR

The MIC2211 is a dual μCap low dropout regulator. The first regulator is capable of sourcing 150 mA, while the second regulator can source up to 300 mA. Ideal for battery operated applications, the MIC2211 offers 1% accuracy, extremely low dropout voltage (80 mV @ 100 mA), and extremely low ground current (only 48 μA total). Equipped with TTL logic compatible enable pins, the MIC2211 can be put into a zero-off-mode current state, drawing no current when disabled. Separate enable pins allow individual control of each output voltage. The MIC2211 is a μCap design, operating with very small ceramic output capacitors for stability, reducing required board space and component cost. The MIC2211 is available in fixed output voltages in the 10-pin 3 mm × 3 mm MLF™ leadless package. The MIC2211 is a high performance, low quiescent current, power management IC consisting of two μCap low dropout regulators. The first regulator is capable of sourcing 150 mA at output voltages from 1.25 V to 5 V; the second regulator is capable of sourcing 300 mA of current at output voltages from 1.25 V to 5 V.
