I am trying to simulate the circuit from this 1993 laser driver paper.
The precision shunt voltage reference is LM399.
How do I include this in the schematic?
I have searched everywhere but could not find a reliable solution or alternative.

Best.
LM399
Production
The LM199/LM399 precision shunt reference features excellent temperature stability over a wide range of voltage, temperature and operating current conditions...
