LR8341A-T50 from LR, in a SOT-23-3L. 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 / VSS return. All voltages are referenced to this pin. Labeled VSS on the SOT23-3L pin assignment diagram and GND on the block diagram.
2	VOUT	power_out	Regulated 5.0 V output (T50 variant). Nominal accuracy ±2% (VOUT0.99 to VOUT1.01) at IOUT=10 mA. Deliver up to 100 mA (160 mA absolute max). Requires a small output capacitor (~1 µF) for stability.
3	VIN	power_in	Unregulated input supply. Recommended operating range VOUT+2 V to 40 V; absolute maximum 55 V. Bypass with ~1 µF ceramic capacitor to GND.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lr8341a-t50.step`	59 KB	You want the bare part, or you mark your own boards.
`lr8341a-t50-etched.step`	1.8 MB	You want the part with `LR8341A-T50` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 456 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.
