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 ...

IC references are popular with circuit designers because they are accurate and exhibit low drift. Some of my future columns will cover the three types of IC references: buried zener, bandgap, and XFET ...

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 ...

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 ...

[Kevin] doesn’t stock zener diodes anymore. Why? Because for everything he used to use zeners, he now uses TL431 bandgap voltage references. These look like zener diodes but have an extra terminal.

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 ...
