MIC5316 Datasheet | Micrel Semiconductor

Description Features 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 300m A LDOs, input voltage down to 1.7V, ultra low drop out of 85m V 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-offmode current state, drawing virtually no current when disabled. The MIC5316 is available in fixed output voltages in the 12-pin 2.5mm x 2.5mm Thin MLF® leadless package.
