I strongly urge you to replace the 7805 and parallel
resistor with an
LM323T unit. The pinout and package are the same, but the current
rating is 3A, not 1. This would give you a measure of protection
that the resistor + 7805 does not afford.
But where do you get 3 amp heat sinks? All I ever see are the wimpy
heat sinks.
There are, of course, other regulator option, but the
LM323T is the
simplest.
