L7815ABD2T-TR

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · D2PAK

L7815ABD2T-TR from STMicroelectronics, in a D2PAK. 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 DC input supply. VI up to 35 V absolute maximum (for VO ≤ 18 V variants). A 0.33 µF ceramic input capacitor is recommended close to the pin when the regulator is far from the supply filter.
2 GROUND power_in Common ground / reference return. Electrically connected to the metal tab of the D²PAK package, which also serves as the thermal pad for heat sinking.
3 OUTPUT power_out Regulated 15 V ± 2% output, up to 1.5 A with adequate heat sinking. A 0.1 µF ceramic output capacitor is recommended to improve transient response.

Two STEP files. Same geometry, different body top:

File Size Use it when
l7815abd2t-tr.step 108 KB You want the bare part, or you mark your own boards.
l7815abd2t-tr-etched.step 1.9 MB You want the part with L7815ABD2T-TR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 501 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:

  • Datasheet: STMicroelectronics datasheet (55 pp, sha256 ca2cee3c82e6b40e, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
