⚡Install this component
Paste this into Claude Code (VS Code panel, Adom editor, or terminal) to install:
Search the Adom Wiki for the library component "TL431" (slug: tl431) at https://wiki-ufypy5dpx93o.adom.cloud/wiki/libraries/tl431. Pull down the KiCad symbol, footprint, and 3D model files from the wiki page's assets. Install them into my current KiCad project and register in sym-lib-table and fp-lib-table. If the page has a datasheet URL, save that too.
The TL431 is a programmable shunt voltage reference from TI. Adjustable from 2.5V to 36V with 0.5% initial accuracy. Used in power supply feedback circuits, voltage references, and current limiters.
