Hello I would like to ask a question. I have a circuit which need 2 different voltages. 7.6V and 3.6V. I would like to take the voltages from a PC Power Supply which has 12V and 5V. Which when measured with a multi meter are truly 12v and 5v.

My Problem is this.

How can I get 7.6V from 12V and 3.6V from 5V (all I want is to reduce the voltage BUT I need 500mA for both. (I do not think I can make a Variable resistor for each because 500mA is a lot. BUT Im not sure anyway. all I want is the 3.6V and 7.6V.

Thanks a lot and hope it isn't much.

Hi xenobius, why don't you just use an adjustable voltage regulator :).

Here is a regulator and some schematics:
