The picture shows the basic voltage regulator composed of zener diode. In the circuit, the R is current-limiting resistor. The RL is loading resistor. The VS is zener diode which is used as the adjustable element. It should note the connecting method when using, which is that it should be reversely connected to the circuit. The circuit regulator process is simply introduced here: when the U1 is increasing to cause the Uo to be bigger, the VS's current Iz is increasing, so the voltage drop on the R is increasing. Thus it keeps the stability of Uo. The same, when the U1 reduces to cause the Uo to reduce, the Iz is also reduced. Then the voltage drop on R is reduced to keep the stability of Uo. The picture shows the basic voltage regulator composed of zener diode.
