The TL431 is a 3 terminal "buried zenar" adjustable CURRENT sink regulator as opposed to a pass
type voltage regulator.  Using the data sheet formula one can trim them to say 25 volts using just
two resistors.  Then they can be stacked in series like a two terminal zenar. Got the idea from
Dr. Jerry.  Haven’t had the time to do it myself yet.    Regards, Perrier
