Do I need more than one 7805 regulator?

I want to power my 5v screen, 5v audio amp, and 5v snes with one 7805 regulator. Is this possible without blowing things up or do I need separate regulators? And how would this be accomplished?

I'm pretty sure you'd need more than one, wire them in parallel. Or just use one or two PTH08000s which don't make heat like the 78xx series of linear regulators does.
