The MIC5316 is a high performance, dual low input voltage, low dropout regulator with Power on Reset (POR) and voltage select. Major features include two 300mA LDOs, input voltage down to 1.7V, ultra low drop out of 85mV at full load, Power on Reset, 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 further save power while in stand-by mode. An adjustable delay time POR output is provided for the second regulator for design flexibility.
Ideal for battery operated applications; the MIC5316 offers 1% accuracy and low ground current to increase light load efficiency. The MIC5316 can also be put into a zero off-mode current state, drawing virtually no current when disabled.
Additional Features
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
Voltage select function
Power on Reset output with adjustable delay
Stable with 1µF ceramic output capacitors
Very fast transient response
Thermal shutdown and current limit protection
