Hi,

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

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.
