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 ...

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 ...

People often forget that many voltage regulator ICs have an upper limit (usually 35 V) on the input voltage they can handle. That applies primarily to types with a fixed output voltage. Adjustable ...

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 ...

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 ...

[Kevin Darrah] wanted to make a simple 3.3V regulator without using an integrated circuit. He wound up using two common NPN transistors and 4 1K resistors. The circuit isn’t going to beat out a cheap ...
