CAD (KiCad official)

  • Symbol: L78L10A
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: l78l10a-etched.step / l78l10a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); l78l10a.step / l78l10a.glb are the bare package body.
