We submerge somewhat deeper into analysis of the seemingly simple TL431 voltage reference with transconductance amplifier to find that some useful design parameters are missing from the manufacturer ...

There are many circuits for low voltage regulators. For higher voltages, such as supplies for valve circuits, the situation is different. That’s why we decided to design this simple regulator that can ...

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 ...

[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 ...

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 ...

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 ...

National’s family of Simple Switcher step-down voltage regulators offers a wide input voltage range from 4.5V to 42V, which allows for wide-voltage transients from 12V and 24V input rails. Internal ...
