MIC5316
Low Voltage Dual 300mA LDO with
Power on Reset and Voltage Select
General Description
Features
The MIC5316 is a high performance, dual low input
300mA output current for each LDO
voltage, low dropout regulator with Power On Reset (POR)
Dual low voltage regulator inputs: 1.7V to 5.5V
and voltage select. Major features include two 300mA
Low output voltage range: 0.8V to 2.0V
LDOs, input voltage down to 1.7V, ultra low drop out of
Ultra-low dropout voltage of 85mV @ 300mA
85mV at full load, Power on Reset, and voltage select.
Voltage select function
Each LDO has its own low voltage input for system
flexibility. The low input voltages and low drop out
Power On Reset output with adjustable delay
operation provides high efficiency by reducing the input to

loss. Voltage select is incorporated into the second output,
Thermal shutdown and current limit protection
which reduces the output voltage to further save power
while in stand-by mode. An adjustable delay time POR
