I'm running a 7805, to supply 5v to a 2732, and 2 74LC 161s, all the load is a LED with a 1K inline resistor. The 7805 is really hot after just seconds, I've checked my wiring a jillion times, ans still that way. Can this 3 chips be drawing that much current?. Grumpy This is for the ecm bench, and when "proven" will be ready for prime time (FTP).
