Hi,

I have downloaded ltspice model of tl431a from link below,but I am getting below error.Attached symbol below.

Hi Sam,
Welcome to AAC.
We need the LTS asc file, please upload.

The model file is not in the folder where LTspice expects to find it.

 

The TL431 model file should be in the LTspice sub folder.

Place the .asy and .lib file in the same folder as the schematic (.asc) file.
Then, place this directive on the schematic:

.inc TL431.lib

or

.inc TL431.mod

so LTspice can find the TL431 subckt.

Place an .inc directive for ONE file only. It doesn't matter which file because they are both the same.

 

My suggestion is if you want the TL431 to be available like any other component in LTspice.

eetech00's suggestion requires you to add the .inc command for every circuit where it is used.

Yes. but you've made a few assumptions and didn't provide complete instructions.

Yes. but at least it will allow the TS to quickly continue with the simulation.

What assumptions and what instructions?

 

What assumptions and what instructions?

For example,
Do you know which version of LTspice is being used?
Does the user know where the sub folder is located? Or the folders significance?

How does that affect my suggestion?
I believe the location of the model file is the same in all versions.

Does the user know where the sub folder is located? Or the folders significance?

Don't know, of course.
But if he doesn't then I would expect him to ask.

No.

Either solution will work. Just a matter of how many follow up questions to answer.
I prefer a minimal amount of follow up answers.

 

No.

Really?
In my IV and XVII versions they both are in the SUB folder.
Where do they go in your versions?

To each his own.
