BL8071GCLATR33

BL Shanghai Belling · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

BL8071GCLATR33 from BL Shanghai Belling, in a SOT-223. 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 VDD power_in Supply voltage input. Operating range 1.5V to 6V (absolute max 6V). Bypass with a 4.7uF input capacitor to GND close to the pin.
2 GND power_in Ground / device return. Also serves as the primary thermal path through the SOT-223 tab.
3 VOUT power_out Regulated output voltage. For the -33 order code the output is fixed at 3.3V ±2%, capable of sourcing up to 1.5A. Decouple with a 4.7uF output capacitor to GND.

CAD (KiCad official)

  • Symbol: BL8071GCLATR33
  • Footprint: Package_TO_SOT_SMD:SOT-223-3_TabPin2
  • 3D model: SOT-223 (KiCad packages3D, STEP)
  • 3D model files: bl8071gclatr33-etched.step / bl8071gclatr33-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bl8071gclatr33.step / bl8071gclatr33.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
bl8071gclatr33.step 64 KB You want the bare part, or you mark your own boards.
bl8071gclatr33-etched.step 2.6 MB You want the part with BL8071GCLATR33 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 621 faces against 75 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: BL Shanghai Belling datasheet (7 pp, sha256 0528b69fe3abe418, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
