There are many LM317 models at the LTspice Groups.io
Yes, looks correct. Thanks!Below is an LTspice simulation of my standard LM317 models, showing what I was referring to:
Note that the output voltage is constant and operation of the regulator appears normal, even thought the input to the LM317 goes to 100V, well above its maximum rating.
I doubt there is any significant difference between the LM317 model and the LM317H model.
