	You are right again Andy! I didnt knew about that suffixes and preffixes, this helps a lot... I think the "H" may be because it is 5A isnt it? I'm trying to find the LM78H05K in the National website. Searching for 7805 it finds... Searching for 78H05 not! What strange! Fake IC? Thanks Andy!

                     You can make your own ...              01/01/70 00:00

                           Yes, they did, and those sheets were excellent!              01/01/70 00:00

   Fairchild was the original manufacturer              01/01/70 00:00
   these parts are hybrids ... so you can synthesize them              01/01/70 00:00
