This video provides a basic tutorial on the L7812CV voltage regulator. The video demonstrates how to connect the regulator to a power supply and multimeter, and then shows how the regulator stabilizes the output voltage to 12 volts. The video also mentions that the data sheet for the regulator will be linked in the description.

The video demonstrates how to use a 7812 voltage regulator IC to reduce noise from fans in a two-channel amplifier. The speaker explains the problem with the fans running at high speed and shows how the IC can regulate the voltage to 12 volts, reducing the noise. The speaker also discusses other potential applications for the IC, such as LED lights and tone controller boards.

The video reviews a 12-volt DC voltage regulator board. The reviewer initially planned to test the board's regulation and ripple, but discovered a major flaw: the bridge rectifier was installed backwards. This led to one of the boards overheating and failing. The reviewer then tests the second board, which appears to be working correctly. The video concludes with a discussion of the board's performance under load and its overall suitability for various applications.
