TL432 from Shikues, 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. Internally compared to the 1.24V bandgap reference; connect to the tap of the R1/R2 divider from cathode to anode to program the regulated cathode voltage per VKA = VREF(1 + R1/R2) + R1IREF. Input current typ ~200 nA.
2	A	passive	Anode. Return terminal of the shunt reference; typically connected to circuit ground. Sinks the cathode current (0.1 mA to 100 mA) that flows from cathode through the device.
3	K	passive	Cathode. Regulated node; pulled up through an external resistor to the supply. Maximum cathode voltage 18 V, continuous cathode current up to 100 mA; dynamic impedance ~0.5 Ω.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tl432.step`	59 KB	You want the bare part, or you mark your own boards.
`tl432-etched.step`	918 KB	You want the part with `TL432` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 232 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.
