Description

The MIC2219 is a dual |Cap 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 48A 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 bring- ing out the feedback nodes to two external pins, allowing for dynamic adjustment of the LDO output voltages.

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

The MIC2219 is available in fixed output voltages in the 10-pin 3mm ! 3mm MLF leadless package.
