lm317 vs lm217 what is the difference?
Kleinstein:
Much of the LM3xx, LM2xx and LM1xx series are parts specified for different temperature ranges. The LM3xx are the cheaper ones for the more normal temperature range. The LM1xx are for the more milittary temperature range. The actual silicon may the the same. Differences are more in testing and the case.

You know that there are these things called “datasheets” that will tell you?

Admittedly, with some parts and some datasheets it’s extremely hard to spot the differences, and I have on occasion encountered parts where only a query to the manufacturer revealed the difference.

But in this case: https://www.st.com/resource/en/datasheet/lm217.pdf

you really think id not have asked before looking over the datasheets?  |O

@innkeeper, I'm with you here. The TI datasheet only mentions LM317.
@tooki, try to keep your mood under control.

Historically, National Semiconductor (now TI) parts were named LM1xx, LM2xx(x) and LM3xx for military, automotive and consumer temperature ranges.
Otherwise, there's no difference.
