Microchip Technology, Inc. Low Vin/Vout Dual 300mA LDO with Vselect MIC5315

The MIC5315 is a high performance, dual low input voltage, low dropout regulator with voltage select. Major features include two 300mA LDOs, input voltage down to 1.7V, ultra low drop out of 85mV at full load, 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 a lower level to further 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 efficiency. The MIC5315 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 Stable with 1 µF ceramic output capacitors Very fast transient response Thermal shutdown and current limit protection
