Transistorized Voltage Regulator (Zener & Transistor)

Transistorized Voltage Regulator (Zener & Transistor)

Transistorized Voltage Regulator Why use a transistorized voltage regulator? If we use a half or a full-wave rectifier we can convert an AC voltage in a DC one.┬áThis converted voltage is unregulated, because the output voltage is not constant and can change due to variations of the load value. To reduce these variations we connect […]

Transistor - Zener Voltage regulator circuit

Transistor – Zener Voltage regulator circuit

Transistor – Zener diode Voltage regulator circuit

This circuit delivers an output voltage established by the voltage of the zener diode less 0.7 volts. The 0.7 volts is the average voltage drop between the base and the emitter of a transistor. (Vbe)
