We often use a Zener diode in a lot of the electronic circuits. For instance, power supplies, voltage detectors, etc. It is so helpful device in electronics. But…Do you understand good enough? Today we will learn Zener diode principle working and example applications usage.
This is a simple zener diode regulator circuit ,Simple Fixed regulator, multiple output voltage are: 12V, 15V, 30V
Let's make the Zener diode with yourself!
For control the voltage battery is steady, output is fixed to 8V, low ripple voltage about 1 mV at input voltage changing between 10V to 30V
This is four circuits of LED voltage indicator are simple and easy to builds for check voltage battery and others, use as zener,transistor,LM339 and more
