Micrel has introduced a family of low input voltage capable, low dropout regulators where each device integrates two LDOs capable of operating from an input voltage as low as 1.7V, while consuming only 37µA total quiescent current. 

Each one of the dual regulator can supply up to 300mA of output current, while only consuming 37µA total quiescent current when both channels are enabled.

The MIC5313/4/5/6 product family allows use of very small ceramic output capacitors, which reduces required board space and component cost.  The product family is available in fixed output voltages.

In addition, this family offers high PSRR, POR, voltage scaling, fast turn-on time, current limit and thermal shutdown protection, and can operate from -40˚C to 125˚C. 

The MIC5313/15 is offered in a 2x2mm Thin MLF 10-lead, and the full featured MIC5314/16 is offered in a 2.5x2.5mm Thin MLF 12-lead package.
