MIC2219
Dynamically Adjustable Dual
Cap LDO
General 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.
