For the longest time, Zener diode regulators have been one of those circuits that have been widely shared and highly misunderstood. First timers have tried to use it to power up their experiments a… ...

The final voltage-reference change is 110+37.5+50=197.5 mV. Some people say that this analysis is not the most rigorous, and they are right, but it gives you an idea of what using a zener reference ...

There was a time when the Zener was a reasonable way to regulate a voltage inexpensively and easily. Unfortunately the regulation characteristics were not very good, and the power lost was very high.

Circuit to limit voltage to a maximum of 1.5 V across dissipation limited devices with symmetrical limiting and a 2 A current rating.
