VOLTAGE REGULATOR

VOLTAGE REGULATOR. Voltage Regulator. Zener diode is a voltage regulator device because it is able to fix the output voltage at a constant value (DC voltage). R S is to limit the zener current, I Z so that it is less than the maximum current, I ZM (to avoid the zener diode from broken).
