MIC5314

Low Voltage Dual 300mA LDO

with Power on Reset

General Description

Features

The MIC5314 is a high performance, dual low input

voltage, low dropout regulator with Power On Reset

(POR). Major features include two 300mA LDOs, input

voltage down to 1.7V, ultra low drop out of 85mV at full

load, and Power On Reset. 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. An adjustable delay time POR

output is provided for the second regulator for design

flexibility.

• 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

• Power On Reset output with adjustable delay

• Stable with 1µF ceramic output capacitors

• Very fast transient response

• Thermal shutdown and current limit protection

• Tiny 12-pin 2.5mm x 2.5mm Thin MLF^®package

Ideal for battery operated applications; the MIC5314 offers

1% accuracy and low ground current to increase light load

efficiency. The MIC5314 can also be put into a zero-off-

mode current state, drawing virtually no current when

disabled.

Applications

• Mobile Phones

• GPS and Navigation Devices

• Portable Media Players

• Digital still and video cameras

• PDAs

The MIC5314 is available in fixed output voltages in the

12-pin 2.5mm x 2.5mm Thin MLF^®leadless package.
