TLV70450DBVR from Texas Instruments, in a SOT-23-5. 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	GND	power_in	Device ground reference. All voltages are referenced to this network ground terminal.
2	IN	power_in	Unregulated input voltage. Operating range 2.5 V to 24 V; absolute max -0.3 V to 24 V. A 0.1-µF input bypass capacitor to GND is recommended.
3	OUT	power_out	Regulated output voltage (5.0 V nominal for TLV70450). Current internally limited; rated for up to 150 mA. Requires an output capacitor greater than 1 µF between this pin and GND for stability.
4	NC	unconnected	Not internally connected. May be left open or tied to GND for improved thermal performance.
5	NC	unconnected	Not internally connected. May be left open or tied to GND for improved thermal performance.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tlv70450dbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`tlv70450dbvr-etched.step`	1.9 MB	You want the part with `TLV70450DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 483 faces against 102 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.
