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 ...

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 ...

The Zener diode is similar to a general-purpose signal diode which consists of a silicon PN junction. It is a special kind of diode in which current is allowed to flow in the forward direction in the ...

Fixed voltage Positive and Negative regulator ICs are used in circuits to give precise regulated voltage. 78 XX series regulator IC can handle maximum 1 ampere current. The Regulator ICs require ...

In a fashion similar to using stacked Zeners for voltage regulation, this LED circuit cleverly combines voltage reference and voltage indication. Fig 1. This voltage regulator circuit (a) uses green ...
