Change small voltage to 1.75 volts

I have an idea for a power generator. The only problem is that it will release small amounts of voltage that will range from 0-2 probably. What I need to do is make this voltage change to exactly 1.75 volts. How could I do this?

There are Voltage regulators that do about the same thing - you can possibly google the kind you are specifically looking for.
