Hello all, I've been chasing my tail trying to find a TL783 model for LTSpice. I am very new at this and I found some files but can't seem to get it to work:
http://www.rocklinger.se/Elektronik/Simulering/LT_Spice_models_en.html

Any help on pointing me to some files would be appreciated (or how to do it properly)

Hello,

Did you put the files in the correct directory:
Place include files and library in catalogue: "..\lib\sub"

Thanks Bertus. The thing is that when I go to the above website and click on those files all I get is a text document poping up which I assume I should copy and paste somewhere. But what is that file? Is it a .asy, .lib, .sub...??? If I paste it into the "comment" as a Spice directive I get an error message. The part is pointing to that directive as far as I know

 

Hello,

When you are on a site and click with the left mousebutton on the link, it will show you a pop-up with the text "save file as" in it.
When you click on that it will ask you where to save it.

hi les,
Place these two files on your desktop, rename the TL783.txt as TL783.inc and double click the 'asc' file.

To see what is in them open with a word pad program

Added a sim run image.
Note: he has used the LM317 'sym' model

 

Thanks guys, I figured it out! I used an existing .lib file, deleted content and pasted TL783. Saved it under TL783.lib and placed into the lib\sub directory. Rename the xreg part as TL783C as described in the subcircuit file add spice directive .lib TL783.lib. Hit Run, it worked! It's all here:

Just have to figure out the LM7824 now...

I found a x_lm78xx.sub file from my recent library download. Is there a way to use this as a lm7824? I don't see a x_lm78xx.asy file or symbol for this?

 

hi les,
If you post a copy of that 'sub' file we can tell you what is in it.
You may have to change the .sub extension to .txt , so that you can upload it.

Here it is: x_lm78xx.txt
