Hello, I've searching in google for these two ASY files so I can use them in my circuit.

I'm fairly new at this and I dont know if I'm doing this right so any tips you can give will be trully welcome.



thank you in advance.

Yes, I need the symbols for those components so i can use them in my circuit.
I was trying to modify the symbol of a LM317 and turn it into lm78l12 or etc.
I may very possibly be doing this wrong so this is where I need help to make those symbols and make them operational.

By the way, I already have the .sub file for every component I meantioned in my post.

Hope I made myself clear!
Thank you

See my LTSpice Tutorial:
http://www.simonbramble.co.uk/lt_spice/ltspice_lt_spice.htm

You want part 4 - LTSpice can create a symbol for you - it is much easier than doing it yourself. It dont look pretty, but it is good enough!

let me know how you get on

just make sure you import the part as a SUBCKT and ensure the part prefix is X (this is all explained on the web page). Then you should not have too many problems

Why bother to simulate a voltage regulator IC? Simply use a voltage source instead.
