I¡¯d be interested in whatever you find, and hope that the transistor-based model you mentioned and I saw works more like an actual LM317. ?

I didn't check the LM317A. I hadn't appreciated this was a new device. Traditionally, the "A" suffix denoted a tightened tolerance of the basic device. More recently, TI started using it for completely different new versions of legacy devices. Not smart and quite misleading. I'll check that the new model But given that PSRR is stated to be not modelled, I hardly see the point of it.
Sometimes I think that people lose the plot. (If you'll pardon the pun.) ?
