MIC5313

Low Voltage Dual 300mA LDO

General Description

Features

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.

• 300mA output current for each LDO

• Dual low voltage regulator inputs: 1.7V to 5.5V

• Low output voltage range: 0.8V to 2.0V

• Ultra-low dropout voltage of 85mV @ 300mA

• Stable with 1µF ceramic output capacitors

• Very fast transient response

• Thermal shutdown and current limit protection

• Tiny 10-pin 2mm x 2mm Thin MLF^®package

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.

Applications

• Mobile Phones

The MIC5313 is available in fixed output voltages in the

10-pin 2mm x 2mm Thin MLF^®leadless package.

• GPS and Navigation Devices

• Portable Media Players

• Digital still and video cameras

• PDAs
