Device Overview

Summary

The MIC2219 is a dual µCap low dropout regulator. The first regulator is capable of sourcing 150mA, while the second regulator can source up to 300mA.

Ideal for battery operated applications, the MIC2219 offers 1% accuracy, extremely low dropout voltage (80mV @ 100mA), and extremely low ground current, only 48µA total. Equipped with TTL logic compatible enable pins, the MIC2219 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 additional feature incorporated in the MIC2219 is bringing out the feedback nodes to two external pins, allowing for dynamic adjustment of the LDO output voltages.

The MIC2219 is a µCap design, operating with very small ceramic output capacitors for stability, reducing required board space and component cost.
