I have an Apple power supply which gives out around 16-18V. I want to use it and reduce the voltage to 9V regulated. Would an LM7805 do the job (with a few extra bits of course) or would another regulator be better. Another idea might be to have a choice of either 12V or 9V. If anyone has a circuit it would be helpful .
Any suggestions would be appreciated
Thanks
Brian
