Me neither.

I would have thought a bog standard part like a 317 would be available.

I was wrong

As someone who worked in the semiconductor industry and in production fabs to create IC devices please take my word for it that modeling is not a simple task and requires an intimate knowledge of analog circuit design. Most parts today are modeled and simulated on a computer before the first die is ever built (therefore can be exported with SPICE). Parts like LM317 were designed in the 1970's......think about the computing power that was available back then. Totally different ways to build things from then to now, so common parts like the 317 would be required start a model from scratch to replicate the device and hope that no mistakes are made.....that takes time and money.....so the probability is low that it will come from the source........which leaves users to do it.......therefore......who has that kind of time?

Hello, I don´t speak English.

But I need LM337 too.

Do you have it? 

Please.
