General Description

The MIC5313 is a high performance, dual low input

voltage, low dropout regulator. Major features include two

300mA LDOs, input voltage down to 1.7V, ultra low drop

out of 85mV at full load. Each LDO has its own low voltage

input for system flexibility. The low input voltages and low

drop out operation provides high efficiency by reducing the

input to output voltage step which minimizes the regulator

power loss.

Ideal for battery operated applications; the MIC5313 offers

1% accuracy and low ground current to increase light load

efficiency. The MIC5313 can also be put into a zero-off-

mode current state, drawing virtually no current when

disabled.

The MIC5313 is available in fixed output voltages in the

10-pin 2mm x 2mm Thin MLF

Data sheets and support documentation can be found on
