In the old days every instrument or system had a power supply board with discrete, homemade regulators on it to power the system. Then IC’s like the LM7805 series of voltage regulators changed ...

[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 ...

Targeted for use in offline AC/DC switched-mode power supplies, three current-mode, fixed-frequency switching regulators from ON Semiconductor incorporate an avalanche-rated 650-V MOSFET that improves ...

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 ...

Linear voltage regulators are key components in any power-management system that requires a stable and ripple-free power supply. A subset of linear voltage regulators is a class of circuits known as ...

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 ...

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 ...
