Which 7" touchscreen are you using that has that low current draw? Is that when the screen is "populated" or blank?

Recommends or maximum of 500ma?  That seems like a very high
number and I'd expect it to be seriously bright.

The reason I ask as my 7" touch screen all total draws less than that with a
HDMI interface(video)  and USB( touch screen). 

As to 7805 heat... Keep it under 70C (168F) as the device has a thermal shutdown
and it lives longer.
