Here are some circuit designs of IC 7805 to monitor the output voltage. 1.This is the manipulation of the Regulator IC 7805 to give 9 volt regulated output. Normally the pin2 of the regulator IC is ...

I certainly agree with you that a Zener diode could be used in the typical Zener regulator circuit, but it would be slightly more helpful to point to his mistake. In his example Vin=5V, Vout=3.3V ...

This voltage regulator delivers smooth control of a constant voltage from 0 to 8 V. It protects the load against short circuits and indicates connection, overload, and output level. The series ...

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, ...

Transistor VT2 provides the regulator short-circuit protection. ... The circuit is similar to using a Zener diode for voltage regulation.

If you tie the reference pin to the cathode, the TL431 does behave like a zener diode that has a breakdown voltage of 2.5 V, ... “The basic circuit is a voltage regulator, ...

By incorporating semiconductor diodes into voltage regulation circuits, engineers can design systems that automatically adjust the output voltage to maintain stability. One common application is in ...
