ILE4264-2G from IKSEMICON, in a SOT-223. 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	I	power_in	Input voltage pin. Operating range 6 V to 28 V (absolute max -42 V to +45 V). Block to ground directly with a ceramic capacitor (100 nF recommended); an additional bulk electrolytic (e.g. 470 uF) may be added for long supply lines.
2	GND	power_in	Ground reference. Ground pin current rated up to 50 mA. Tied together with pin 4 (tab) as the common ground/heat-sink.
3	Q	power_out	Regulated 5 V output, 100 mA continuous (up to 150 mA capability). Requires an output capacitor CQ >= 10 uF with ESR <= 4 ohm for loop stability; tantalum or MLCC suitable. Absolute max output voltage rating -0.3 V to +32 V.
4	GND	power_in	Ground / thermal tab of the SOT-223 package. Electrically connected to pin 2; solder to a copper pour for heat dissipation (Rth j-a = 220 C/W without heat sink).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ile4264-2g.step`	64 KB	You want the bare part, or you mark your own boards.
`ile4264-2g-etched.step`	1.6 MB	You want the part with `ILE4264-2G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 402 faces against 75 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.
