TPTLV70450DBVR from TECH PUBLIC, 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	Ground reference for the regulator. Connect to the system single-point ground.
2	VIN	power_in	Power input voltage. Accepts 3V to 36V (absolute max 40V). A 1µF input capacitor (C1) is recommended close to the pin.
3	VOUT	power_out	Regulated output voltage (fixed per ordering suffix, e.g. 5.0V for -50). Supplies up to 150mA (typ), with a 1µF output capacitor (C2) required for stability.
4	NC	unconnected	No internal connection. Leave floating or tie to GND per board convention.
5	NC	unconnected	No internal connection. Leave floating or tie to GND per board convention.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tptlv70450dbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`tptlv70450dbvr-etched.step`	2.1 MB	You want the part with `TPTLV70450DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 532 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.
