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 ...

Fixed voltage Positive and Negative regulator ICs are used in circuits to give precise regulated voltage. 78 XX series regulator IC can handle maximum 1 ampere current. The Regulator ICs require ...

This article was prompted by a friend of mine asking for help on a board with an ESP32 heart. The board outputs 2.1 V instead of 3.3 V, and it doesn’t seem like incorrectly calculated feedback ...

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 ...
