TLV431: common questions
Where can I find a TLV431 reference design?
Each of the 5 boards on this page is a real design using the TLV431. 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 TLV431 use?
Most are built on AVR/Arduino (2), RP2040/RP2350 (1) and STM32 (1).
How big is a typical board using the TLV431?
The median is 66 × 99.1 mm, and 80% are two-layer designs.
What is the most popular open source board using the TLV431?
By GitHub stars, Mobile-Whip by skuep, with 88 stars.
Can I simulate one of these boards using the TLV431 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.
