Zener diode voltage regulator calculator

Output: Resistance: Ohms, Watts. Enter value and click on calculate. Large atomizing spray nozzle covers 360°.

In this circuit diagram, the unregulated input voltage is VS, and the regulated output voltage across the load is “VL”, which is the same as that across the . EEVblog Online references, utilities, calculators etc.

Like any semiconductor device, the zener diode is sensitive to temperature.

To designing the electronic circuits along with Zenor diodes, the resistance and power rating calculation is necessary.

To calculate exact operating point, i. Does selecting different values of resistors affect the circuit performance? In the above circuit diagram excess voltage (Vin – Vz) will drop across Rs thus by limiting the current through Zener. For the proper designing of the regulator we should know,. As the breakdown voltage is approached the current.

Linear voltage regulators control the voltage drop between input and output as needed to set the desired output voltage. Mathematically analyze the circuit , solving for all voltage and current values. Carefully measure all voltages and currents,.

Qualitatively determine what will happen to the series resistor current and the zener diode current in this voltage regulator circuit if the load current suddenly decreases. Assume that the zener diode's . The zener circuit works without load. Zener diode : V, Power rating: W . This means that the zener diode must be able to dissipate the power that is normally dissipated in the load.

Check the datasheet for the zener for maximum dissipated power. A regular small zener diode is often rated for 400mW. At this point you know the zener voltage . To use our zener diode voltage regulator calculator , enter the requested values below and click the Calculate button. The required value and minimum power rating of the resistor and zener diode will then be .
