A quick and a clean way to derive a 3.3V or 5V regulation or any other desired value from a given higher voltage source is to use series diodes as shown in the following diagram. Using Rectifier Diodes for Dropping Voltage
A Zener diode's ability to maintain almost constant voltage in its breakdown region makes it suitable for regulating voltage even in the simplest voltage regulator applications. A voltage regulator's main role is to deliver a steady output voltage to a load connected in parallel. This is even when the supply voltage has ripples or the load
Zener Diode as Voltage Regulator Tutorial Circuit Diagram
A Zener diode voltage regulator is an electrical circuit that maintains a constant DC output voltage using a Zener diode. A perfect regulator would produce a constant voltage regardless of input fluctuations or load current variations. Zener diode is a popular one in types of diode. Using a Zener diode as a voltage regulator has several advantages. It is a simple, cost-effective, and easy-to-implement solution for voltage regulation. By selecting Zener diodes with different breakdown voltages, various output voltage levels can be achieved. This method works well for low-power applications where minor voltage fluctuations
The zener voltage regulator consists of a current limiting resistor R S connected in series with the input voltage V S with the zener diode connected in parallel with the load R L in this reverse biased condition. The maximum power rating P Z of the zener diode is 2W. Using the zener regulator circuit above calculate: a). The maximum
Voltage Regulator Circuits and Projects Circuit Diagram
The key in using the zener diode as voltage regulator is that as long as the zener diode is reverse biased, the flow of current greater than a few micro amperes must be accompanied by a voltage greater than the Zener voltage. This type of arrangement of the circuit provides safety for equipment connected to terminals. This arrangement of
