AZ432ANTR-TP from TECH PUBLIC, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	REF	input	Reference input pin. Internal error amplifier compares this pin against the internal 1.25 V bandgap; the cathode sinks current to regulate REF to Vref. Typical reference input current 0.4 uA (max 1.0 uA); reference input current range up to 1 uA absolute maximum.
2	K	power_in	Cathode pin. Shunt regulator current-sink terminal; VKA absolute maximum 18 V, continuous cathode current up to 100 mA, minimum cathode current for regulation ~30 uA (typ). Dynamic impedance ~0.15 Ω typ at IK = 0.1 mA to 20 mA.
3	A	power_in	Anode pin. Ground/return terminal for the shunt regulator; all voltage values in the datasheet are referenced to this pin.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`az432antr-tp.step`	59 KB	You want the bare part, or you mark your own boards.
`az432antr-tp-etched.step`	1.6 MB	You want the part with `AZ432ANTR-TP` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 419 faces against 69 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
