Electronics - voltage regulator

    The voltage regulator have 3 legs, 2 for input and one for output to make a constant voltage.

    I was wondering if this is possible?

    2 x input of 12v and can the output be 24v or only under 12v?

    thanks

    If you're talking about the 78xx series voltage regulators, then one of the legs is common. You need to reference the input and output voltages with respect to the common.

    From what I've known, regulator outputs are always less than the inputs. If you're looking for a way to increase a voltage, then you may want to look into DC-DC converters.
