I've never seen a complete collection of his studies available via download. To my knowledge, the only complete versions of them are in physical books - for example in the link Kevin provided. Same for his 12 preludes.

If you are unable or unwilling to purchase the physical scores you can also search the web for tab and MIDI versions like this:

http://www.classtab.org/#ttab
http://www.freetabs.org/classical.htm#Tarrega

Sites like that typically have at least a couple of the studies.
