TLV70433DBVR 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 measured with respect to this pin.
2	IN	power_in	Unregulated input voltage. Operating range 2.5 V to 24 V (absolute max 24 V, −0.3 V min). A 0.1-µF bypass capacitor to GND is recommended close to the pin.
3	OUT	power_out	Regulated 3.3-V output (±2% DC accuracy), 150-mA max output current, internally current-limited (~160 mA min). A capacitor greater than 1 µF between this pin and ground is required for stability.
4	NC	unconnected	Not internally connected. May be left open or tied to ground for improved thermal performance.
5	NC	unconnected	Not internally connected. May be left open or tied to ground for improved thermal performance.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tlv70433dbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`tlv70433dbvr-etched.step`	2.0 MB	You want the part with `TLV70433DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 503 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.
