If I proceed down this path, it will be a learning experience. As with
most learning projects, a bit of 'overkill' is usually present.
It's just plain old fun to over engineer something! :)

The LM399 does look like a nice package. Do they all come with the
thermal shield, or is that an option that needs to be purchased separately?
