From the project
ALPS V1 - Linear regulated PSU 12V 1A with full ripple calculations and design documentation
This is a simple design for a 12V 1A power supply, used more as a project to learn how to use KiCad, learn PCB design rules and make full documentation of every choice and all the theoretical values and calculations for this specific design. I decided to make this project just because it was the first circuit I ever made when I got into electronics in school. For the calculations I use 5 decimals just to make it more "precise". In this project I use 12V because I thought it's the minimum recommended for testing electronics and you can find cheaper transformers for this voltage. This also…
