Zener Diode as Voltage Regulator
Click Here to Download the Circuit Diagram of “Zener Diode as Voltage Regulator”
The Zener Diode as a Voltage Regulator project involves using a Zener diode to maintain a stable output voltage across varying input voltages. The Zener diode operates in reverse breakdown mode, where it maintains a constant voltage (the Zener voltage) regardless of changes in input voltage or load conditions.
In this project, a Zener diode is connected in reverse bias across a load resistor. When the input voltage exceeds the Zener voltage, the diode starts conducting and clamps the output voltage to the Zener voltage. This configuration ensures a stable and regulated output voltage, making it ideal for powering sensitive electronic circuits. Proper heat dissipation and current limiting resistors are essential for optimal performance and reliability.
