Some voltage references can be used as shunt regulators, either by tying V IN and V OUT together or by leaving V IN open. These devices are limited to low currents, however, with a typical limit of ...

Originally, the venerable three-terminal linear regulator featured a bipolar junction transistor emitter-follower output that exhibited very low output impedance. Many of today's applications demand ...

A power converter generates a voltage and current for a load with all the output power coming from the input source – no energy is manufactured inside the converter and some inevitably gets used by ...

[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 ...

For the PDF version of this article, click here. Most offline and telecom power supplies need a method to isolate the relatively high input voltage from lower voltage outputs to provide safety, ...
