MIC5315

Low Voltage Dual 300mA LDO

with Voltage Select

General Description

The MIC5315 is a high performance, dual low input

voltage, low dropout regulator with voltage select. Major

features include two 300mA LDOs, input voltage down to

1.7V, ultra low drop out of 85mV at full load, and voltage

select. 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. Voltage select is incorporated into the second output,

which reduces the output voltage to a lower level to further

save power while in stand-by mode.

Ideal for battery operated applications; the MIC5315 offers

1% accuracy and low ground current to increase light load

efficiency. The MIC5315 can also be put into a zero-off-

mode current state, drawing virtually no current when

disabled.

The MIC5315 is available in fixed output voltages in the

10-pin 2mm x 2mm Thin MLF

leadless package.
