LR7815D

LRC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252

LR7815D from LRC, in a TO-252. 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 VI power_in Unregulated positive input voltage. Recommended operating range 17.5V to 30V for 15V output; absolute maximum 35V. A 0.33 uF bypass capacitor to GND should be placed close to this pin.
2 GND power_in Ground / common return. In the DPAK package this pin is also electrically connected to the metal tab/heatsink slug on the back of the package.
3 VO power_out Regulated +15V output. Delivers up to 1A continuous (peak 1.8A typical); short-circuit current limited to ~230 mA typical at VI=35V. A 0.1 uF output capacitor to GND is recommended for stability and transient response.

Two STEP files. Same geometry, different body top:

File Size Use it when
lr7815d.step 119 KB You want the bare part, or you mark your own boards.
lr7815d-etched.step 1.3 MB You want the part with LR7815D already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 353 faces against 83 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: LRC datasheet (9 pp, sha256 d635b02fe56ffd52, retrieved 2026-08-17, tier: lcsc)
  • 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).
