The three-terminal TL431 voltage regulator is commonly found in switching power converters and instrumentation as a voltage reference. It is seemingly simple, yet has subtleties, including missing ...

Nerd Ralph loves cheap and dirty hacks, and for that we applaud him. His latest endeavor is a LiFePO4 battery charger that he made out of parts he had on hand for under $0.50 US. (Although we think he ...

Download this article in PDF format. Analog semiconductor companies release buck-regulator chips so often you might think nothing of it. Yet there’s an enormous amount of work that goes into getting ...

I'm hoping one of you has personal experience with this one...<BR><BR>http://www.radioshack.com/product.asp?catalog%5Fname=CTLG&product%5Fid=276-1778<BR><BR>I saw ...

[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 ...

Is it possible to design an unconditionally stable linear voltage regulator? In fact, many believe that most regulator ICs are unconditionally stable. The answer is both simple and complex, if it is ...

In this part, we go to greater depths to look at TL431 dynamics. Adjust your air regulator for the deeper dive. What is seen in the data sheet plots of gain and output resistance for some ...
