As a bonus, the circuit can serve as a moderate-voltage, power-limited adjustable dc source. Although conventional multimeters' resistance ranges typically apply enough voltage to forward-bias most ...

The standard and classic is the adjustable positive voltage regulator ... which behaves equivalently to a 1.5V, high-current Zener diode. This concept can provide a versatile and very useful circuit ...

As always, there were a few real-world things to resolve, but the circuit worked as expected. As [Kevin] points out, the faux-zeners are about four for a dollar and even less in quantity. A zener ...

A modification of this circuit adds an opportunity to adjust the window width within the range the diodes provide (Fig. 3). You can also replace diodes Q1 and Q2 with a Zener diode to further ...

Not if you’ve watched [0033mer]’s Simple Electronic Circuit Hacks video! You know just what to do. The ground pin of a LM7805 connects to the cathode of a TL431 programmable Zener diode pulled ...

The circuit is similar to using a Zener diode for voltage regulation. This idea cleverly combines this voltage reference and voltage indication all in one. However, designers should be aware of ...
