TPS60403DBVR 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	OUT	power_out	Negative power output with V_O = -V_I. Bypass OUT to GND with the output filter capacitor C_O (1 µF typical, up to 100 µF). Delivers up to 60 mA.
2	IN	power_in	Supply input, 1.6 V to 5.5 V range. Bypass IN to GND with a capacitor equal in value to the flying capacitor (1 µF typical for TPS60403).
3	CFLY-	passive	Negative terminal of the flying capacitor C_(fly). Connect a 1-µF ceramic capacitor between CFLY- and CFLY+.
4	GND	power_in	Device ground reference.
5	CFLY+	passive	Positive terminal of the flying capacitor C_(fly). Connect a 1-µF ceramic capacitor between CFLY+ and CFLY-.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tps60403dbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`tps60403dbvr-etched.step`	2.5 MB	You want the part with `TPS60403DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 597 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.
