Everything You Need to Know About Thedesktop or laptop Motherboard Voltage Regulator Circuit
By Gabriel Torres
Introduction
If you are willing to learn more about motherboard quality you must deeply study the
voltage regulator circuit, which is in charge of taking the voltage provided by the
power supply – namely +12 V – and converting it into the appropriate voltage required
by the CPU, memories, chipset and other circuits present. In this tutorial we will
present an in-depth trip inside the motherboard voltage regulator circuit, showing you
how to identify this circuit, how it works, what the most common projects are and how
to identify good-quality components.
The quality of the voltage regulator circuit is one of the best ways to have an idea
about the overall motherboard quality and life-span for several reasons. A good
voltage regulator won’t have any fluctuations or noise on its outputs, providing the
CPU and other components with a clean and stable voltage, allowing them to work
perfectly. A bad voltage regulator can lead to fluctuations or noise on the voltage that
will lead to malfunctions like the computer crashing, resetting and presenting the
infamous Blue Screen of Death on Microsoft Windows xp or 7.
