Please disregard. I've solved my needs. Thanks for all the useful replies :)

As posted elsewhere, I am planning to build this low-ohm measuring current source.
Only problem, I can't readily get my paws on an LM385-1.2 voltage reference, or any
of it's assorted flavors (LM185/285).

Can anybody here help me? I need at minimum, 2 pieces.

I'm located in the Pacific Northwest, USA (WA state)

What regulates the 9V output from the 555 converter?
As shown, there is no limit as to how high that voltage can go with a small or no load.
You could add a 9V shunt regulator or Zener to absorb any excess.
