NCP51460SN33T1G from onsemi, 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	VIN	power_in	Positive input voltage. Operating range VOUT+0.9 V to 28 V (absolute max 30 V, reverse -15 V). Typically bypassed with a 0.1 uF ceramic capacitor to GND.
2	VOUT	power_out	Regulated 3.3 V (+/-1%) output voltage. Delivers up to 20 mA. Stable with or without an output capacitor; short-circuit protected (Isc ~80 mA).
3	GND	power_in	Power supply ground and device substrate. Return path for input and output currents; connect to system ground.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ncp51460sn33t1g.step`	59 KB	You want the bare part, or you mark your own boards.
`ncp51460sn33t1g-etched.step`	2.7 MB	You want the part with `NCP51460SN33T1G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 642 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.
