A VRM is an essential part of every computer, but even many computer-savvy enthusiasts don't know what it is or how it works. We'll explain all.

This is the general idea of how voltage regulators work. Luckily there is no need to make one of these for every project because companies sell them in nice little 3 pin packages.

The regulator produces an adjustable output ranging from 0.6 V to 0.85xVIN with 1% accuracy over load and line. Note that both the input voltage range and the output voltage range extend lower ...
