There are times when you need to bias a low-current load and simply didn’t want to add another voltage regulator, or where you need a reasonable level of voltage accuracy, so a simple voltage divider ...

Normally, when you want a low DC voltage from the AC line, you think about using a transformer of some kind. [RCD66] noticed that an AC monitor meter must have some sort of power supply but had no ...

[Afroman] is back again with another great tutorial video on the basics of electronics. This time it’s zener diodes. Page three or four of every ‘beginners guide to electronics’ covers a diode as, “a ...

I need a circuit to limit the voltage across some dissipation limited devices. It must: limit the voltage to a maximum of 1.5 V, have symmetrical limiting, be capable of accepting a current of 2 A, ...

As useful as the rectification properties of diodes are, the forward voltage drop they create can vary widely with temperature. This increases losses and can introduce tolerance errors in power ...
