#012 - Shunt Voltage Regulator Overview (Class-A Headphone Amplifier Project)
Channel: Innove Workshop
Date: 2020-09-27

In this episode of the headphone amplifier series, we take the first steps into designing the power supply of the amplifier.

Since we'll be using a shunt voltage regulator in the final build, as with previous videos I decided to go slowly and build up the knowledge of these kinds of supplies. First we'll take a look at a simple Resistor+Zener diode combination, then we'll improve it by using a transistor, and will end up with a very stable voltage regulator using a current source and the buffered zener.

In the end of the video I gave a little sneak peek of what we'll be seeing in the next video, which will be a bit on an experiment to choose the perfect "low-cost" voltage reference for our regulator.
