For the longest time, Zener diode regulators have been one of those circuits that have been widely shared and highly misunderstood. First timers have tried to use it to power up their experiments and ...

Determine the range of values of Vi that will maintain the Zener diode of the figure above in the “on” state. To solve for Vi(max), we use the formula But, since IR(max) is not yet known, we have to ...

In the old days every instrument or system had a power supply board with discrete, homemade regulators on it to power the system. Then IC’s like the LM7805 series of voltage regulators changed ...

Before there were bandgaps, voltage references ranged from neon glow tubes to Zener diodes. Paul Rako, with the help of Bob Pease and others, “drifts” back in time to trace their history. Back on ...

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 chain ...
