Xenobius Posted October 13, 2004 Report Share Posted October 13, 2004 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. Quote Link to comment Share on other sites More sharing options...
Dazza Posted October 13, 2004 Report Share Posted October 13, 2004 Hi xenobius, why don't you just use an adjustable voltage regulator :). Quote Link to comment Share on other sites More sharing options...
