To get precise voltage to a circuit, the simplest and easy way is to use a Zener diode.It uses the reverse breakdown voltage characteristics to maintain a fixed voltage across it Zener diode ZD is ...

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 ...

It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how to use a ...

According to Microsemi, its new family of ultra-sharp knee Zener diodes offers four times the voltage regulation and a 40-fold improvement in typical lower leakage current versus comparable devices.

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 ...

Powering your gadgets generally seems like a necessary evil. To help with this [Felipe La Rotta] made a really nice bench power supply using a PC power supply and a LM317 adjustable voltage regulator.
