L7815CD2T-TR

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

L7815CD2T-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 positive supply input (Vi). Absolute maximum 35 V for the 15 V version; typical operating range ≈17 V to 30 V. Recommend a 0.33 µF bypass capacitor from INPUT to GND close to the device.
2 GROUND power_in Common ground / return pin. Electrically connected to the D²PAK metal tab, which serves as the primary thermal path (RthJC ≈ 3 °C/W).
3 OUTPUT power_out Regulated +15 V output (Vo, tolerance ±4 % standard, ±2 % on A-grade). Delivers up to 1.5 A with adequate heat-sinking. Recommend a 0.1 µF output bypass capacitor to improve transient response.

CAD (KiCad official)

  • Symbol: L7815CD2T-TR
  • Footprint: Package_TO_SOT_SMD:TO-263-2
  • 3D model: D2PAK (KiCad packages3D, STEP)
  • 3D model files: l7815cd2t-tr-etched.step / l7815cd2t-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); l7815cd2t-tr.step / l7815cd2t-tr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
l7815cd2t-tr.step 108 KB You want the bare part, or you mark your own boards.
l7815cd2t-tr-etched.step 1.8 MB You want the part with L7815CD2T-TR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 465 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:
