Use Google .. it's a great tool !

I put in the little search box "7805 maximum input voltage" - and all sorts of information came back.

Like this link  - http://en.wikipedia.org/wiki/78xx

which says,

"These devices support an input voltage anywhere from a couple of volts over the intended output voltage, up to a maximum of 35 to 40 volts depending on the make"
