LM317T: common questions

Where can I find a LM317T reference design?

Each of the 6 boards on this page is a real design using the LM317T. 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 LM317T use?

Most are built on AVR/Arduino (2).

How big is a typical board using the LM317T?

The median is 127 × 80 mm, and 83% are two-layer designs.

What is the most popular open source board using the LM317T?

By GitHub stars, Power Supply (plus UBBB 32u4 rev 1.2) by thebiguno, with 75 stars.

Can I simulate one of these boards using the LM317T 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.
