L7805: common questions

Where can I find a L7805 reference design?

Each of the 3 boards on this page is a real design using the L7805. 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 L7805 use?

Most are built on RP2040/RP2350 (1), AVR/Arduino (1) and ESP32 (1).

How big is a typical board using the L7805?

The median is 63.4 × 85 mm, and 100% are two-layer designs.

What is the most popular open source board using the L7805?

By GitHub stars, NanoGris by Quinienl, with 41 stars.

Can I simulate one of these boards using the L7805 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.
