LM317: common questions
Where can I find a LM317 reference design?
Each of the 4 boards on this page is a real design using the LM317. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
Which microcontrollers do boards using the LM317 use?
Most are built on AVR/Arduino (1).
How big is a typical board using the LM317?
The median is 74.7 × 70.1 mm, and 100% are two-layer designs.
What is the most popular open source board using the LM317?
By GitHub stars, Alim10o by acmo0, with 14 stars.
Can I simulate one of these boards using the LM317 before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
