## CAD (KiCad official)

- Symbol: `TL331LVDBVR`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `tl331lvdbvr-etched.step` / `tl331lvdbvr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tl331lvdbvr.step` / `tl331lvdbvr.glb` are the bare package body.
