The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 3 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

L7805ABD2T-TR

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-263-2

L7805ABD2T-TR from STMicroelectronics, in a TO-263-2. 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 INPUT power_in Unregulated positive DC input. Absolute max VI = 35 V for 5-18 V output versions. Recommended input capacitor CI = 0.33 uF close to the pin for stability. Dropout voltage ~2 V at IO = 1 A, so VI should be at least VO + 2 V (typ. 7.5 V min for the 5 V part).
2 GROUND power_in Common ground reference for input and output. Electrically connected to the exposed metal tab of the D2PAK, which serves as the primary heat-sinking surface. Quiescent current (~4.3 mA typ) flows out of this pin.
3 OUTPUT power_out Regulated +5 V output, 4.8-5.2 V over line/load/temperature (A version). Delivers up to 1.5 A peak (typically specified at 1 A) with internal current limiting, SOA and thermal-shutdown protection. Recommended output capacitor CO = 0.1 uF for transient response.

CAD (KiCad official)

  • Footprint: Package_TO_SOT_SMD:TO-263-2
  • 3D model: TO-263-2 (KiCad packages3D, STEP)
  • 3D model files: l7805abd2t-tr-etched.step / l7805abd2t-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); l7805abd2t-tr.step / l7805abd2t-tr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
l7805abd2t-tr.step 108 KB You want the bare part, or you mark your own boards.
l7805abd2t-tr-etched.step 2.0 MB You want the part with L7805ABD2T-TR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 531 faces against 79 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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
