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.
Ideal for battery operated applications; the MIC5314 offers

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
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
