General Description

The MIC5306 is a micropower, µCap low dropout

regulator designed for optimal performance in a small

space. It is capable of sourcing 150mA of output current

and only draws 16µA of operating current. This high

performance LDO offers fast transient response and

good PSRR while consuming a minimum of current.

Ideal for battery operated applications; the MIC5306

offers 1% accuracy, extremely low dropout voltage

(45mV @ 100mA).

compatible enable pin, the MIC5306 can be put into a

zero-off-mode current state, drawing no current when

disabled.

The MIC5306 is a µCap design, operating with very

small ceramic output capacitors for stability, reducing

required board space and component cost.

The MIC5306 is available in fixed output voltages in

Thin SOT23-5 packaging.
