A voltage stabilizer is an electronic device able to deliver
relatively constant output voltage while input voltage and
load current changes over time.

The voltage stabilizer is the shunt regulator such as a
Zener diode or avalanche diode. Each of these devices
begins conducting at a specified voltage and will conduct
as much current as required to hold its terminal voltage to
that specified voltage. Hence the shunt regulator can be
viewed as the limited power parallel stabilizer. The shunt
regulator output is used as a voltage reference.
