## CAD (KiCad official)

- Symbol: `LM828M5`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `lm828m5-etched.step` / `lm828m5-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lm828m5.step` / `lm828m5.glb` are the bare package body.
