LN1134A282MR-G from NATLINEAR, 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	VIN	power_in	Regulator input supply. Operating range 2.0 V to 7 V (absolute max VSS+8 V). Requires a ≥1.0 µF input capacitor (C1) to VSS close to the pin.
2	VSS	power_in	Ground / common return for the regulator. Reference node for VIN, VOUT and CE.
3	CE	input	Chip enable. Active-high with internal pull-down resistor on the 'A' variant, so the regulator stays off if CE is left floating. VCEH ≥ 1.6 V enables the output; VCEL ≤ 0.25 V shuts it down. VON/OFF absolute max is VSS-0.3 V to VIN+0.3 V.
4	NC	unconnected	No internal connection on the SOT-23-5 / SOT-353 / SC70-5 package. Leave floating or tie to a stable potential; do not use as a routing via.
5	VOUT	power_out	Regulated 2.8 V output (±2.0 % accuracy). Requires ≥1.0 µF output capacitor (C2, tantalum recommended, 2.2 µF typical). Delivers up to 300 mA when VIN ≥ VOUT+1 V; internal current limiter protects against overload.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ln1134a282mr-g.step`	85 KB	You want the bare part, or you mark your own boards.
`ln1134a282mr-g-etched.step`	2.3 MB	You want the part with `LN1134A282MR-G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 576 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.
