RE: Too hot 7805

Nope, doing so will result in flames :)

You can run them in parallel if you put a load balancing resistor in series
with each regulator, to the tune of about .5 ohms.  If you need more current
than 1 amp, let me know, I built a massive linear power supply for my
workbench that provides +/- 12V @30A and +/- 5V @ 30A, using LM78xx/79xx
using 2n3055 transistors to handle the current.  Its a very simple design,
and I'd have to figure out how to get it out of visio into a format you can
view.

let me know Bruce.  I can snip out the +5V stuff.

Added a .01+10 cap at input and output still gets hot, yes 12V input.

Can I just plug a second 7805 in?.
