Call me stupid if you want, but I can't for the life of me work out how to make a 'negative' LM7805. IE, I have a 9v input and an LM7805 giving me a +5v output.
I want to also have a -5v Supply derived from that +9v input. Any ideas? I think there was an LM337 that does this but it has all sorts of extra components and adjusters in the example circuits I can find. All I want is a simple regulator with a few caps either side
Thanks
