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)
