We don't have anything more modern in that metal can, but here is a link to a filtered version of our parametric search which shows the positive voltage linear regulators that we do have in a metal can.
If you wanted to assess newer options I'd start…
Part Number: LM140L Dear All
I am using the 12V fixed regulator LM140LAH-12 in a simple circuit as in attached file.
The goal is to remove "all" DC-DC ripple for a very sensitive application, extremelly low noise required.
The problem is that…
