MIC5315 Low Voltage Dual 300mA LDO with Voltage Select General Description Features The MIC5315 is a high performance, dual low input ? 300mA output current for each LDO voltage, low dropout regulator with voltage select. Major ? Dual low voltage regulator inputs: 1.7V to 5.5V features include two 300mA LDOs, input voltage down to ? Low output voltage range: 0.8V to 2.0V 1.7V, ultra low drop out of 85mV at full load, and voltage ? Ultra-low dropout voltage of 85mV @ 300mA select. Each LDO has its own low voltage input for system flexibility. The low input voltages and low drop out ? Voltage select function operation provides high efficiency by reducing the input to ? Stable with 1?F ceramic output capacitors output voltage step which minimizes the regulator power ? Very fast transient response loss. Voltage select is incorporated into the second output, ? Thermal shutdown and current limit protection which reduces the output voltage to a lower level to further ? ? Tiny 10-pin 2mm x 2mm Thin MLF package save power while in stand-by mode. Ideal for battery operated applications; the MIC5315 offers 1% accuracy and low ground current to increase light load Applications efficiency. The MIC5315 can also be put into a zero-off- ? Mobile Phones mode current state, drawing virtually no current when disabled. ? GPS and Navigation Devices The MIC5315 is available in fixed output voltages in the ? Portable Media Players ? 10-pin 2mm x 2mm Thin MLF leadless package. ? Digital still and video cameras Data sheets and support documentation can be found on ?

Stable with 1?F ceramic output capacitors output voltage step which minimizes the regulator power ? Very fast transient response loss. Voltage select is incorporated into the second output, ? Thermal shutdown and current limit protection which reduces the output voltage to a lower level to further ? ? Tiny 10-pin 2mm x 2mm Thin MLF package save power while in stand-by mode. Ideal for battery operated applications; the MIC5315 offers 1% accuracy and low ground current to increase light load Applications efficiency. The MIC5315 can also be put into a zero-off- ? Mobile Phones mode current state, drawing virtually no current when disabled. ? GPS and Navigation Devices The MIC5315 is available in fixed output voltages in the ?
