Designing Voltage Regulators with Zener Transistors: The Definitive Guide Circuit Diagram
All linear power supply circuits which are designed to produce a stabilized, constant voltage and current output fundamentally incorporate transistor and zener diode stages for getting the required regulated outputs. These circuit projects using discrete parts can be in the form of of permanently fixed or constant voltage, or stabilized adjustable output voltage. What is a Voltage Regulator A voltage regulator with a transistor usually consists of a bipolar junction transistor (bjt) with high current handling capability in an emitter follower configuration, driven by zener diode and resistor potential divider (PD) network. Transistor - Zener Voltage regulator This circuit delivers an output voltage established by the voltage of the zener diode - 0.7 volts. The 0.7 volts is the average voltage drop between the base and the emitter of a transistor. (Vbe). So, Vout = Vz - Vbe = Vz - 0.7 V. When the unregulated voltage goes up, the zener diode current will also go up. The voltage across the zener diode has
The series voltage regulator can be defined as a regulator which has the limitations like high dissipation, less efficient, and the transistor voltage and Zener diode voltages are affected once the temperature rises. Circuit Design of Transistor Series Voltage Regulator This voltage regulator circuit design is shown below.
