After clocks and resets, we like to focus on voltage regulator circuits when doing an EMC board review. Voltage regulators can cause both radiated emissions and susceptibility problems. Emissions are ...

In Seemingly Simple Circuits: The TL431 Voltage Regulator, Part 2, we looked at how voltage gain of the TL431 is measured. Now we plunge deeper in, to look at closed-loop output resistance, derive ...

An electronic circuit used to maintain a level amount of voltage in an electrical line. It eliminates power surges, spikes and brownouts, which can cause harm to sensitive electronics. A voltage ...

It’s often necessary to connect point-of- load (POL) dc/dc power supply modules in parallel to get a sufficiently high-current output for applications such as test instruments, blade servers, and so ...

QUESTION: There are so many different voltage regulators on the market these days. How do I pick one that will be good for my circuit? ANSWER: Wow, this is a tough question, but also a good one. I’ll ...
