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 ...

Developed as a three-terminal shunt regulator, the popular and multiple-sourced TL431 IC offers designers many intriguing possibilities beyond its intended application. Internally, the TL431 comprises ...

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, ...

The power supply for new products is often taken for granted. However, judging from recent experience, it’s clear that the power supply for new industrial equipment or Internet of Things (IoT) ...

Last month we showed you how to use resistors to reduce voltage. While it's a viable solution for many cases it isn't for others. As noted before, resistors work for devices whose load remains ...

Electronic systems often require multiple voltages to power the various internal circuits. Non-isolated regulators are a common and easy way to convert one voltage to another. Regulators typically ...
