A power supply is a significant tool. Basically every electronic system needs one. Also, it is invaluable in prototyping and testing circuits.
A reliable and robust power supply is essential for any engineer’s toolkit. This project series builds a linear PSU capable of supplying 3.3V – 12VDC at upto 1.2A. It will be based on the popular LM317 with a PNP transistor (MJ2955). Let’s run through the specifications the PSU must have:
Since there is alot of information, this project will be split into two parts.
The first part will focus on the project specifications and designing the majority of the PSU. The 2nd part finishes the design and tests it.
