CAD (KiCad official)

  • Symbol: LT4455
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: lt4455-etched.step / lt4455-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lt4455.step / lt4455.glb are the bare package body.
