BL Shanghai Belling · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

BL8078CC3TR33 from BL Shanghai Belling, in a SOT-89-3. 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 GND power_in Ground reference pin for the regulator. Connect to system ground.
2 VIN power_in Supply voltage input. Operating range 3V-40V (absolute max 50V). Requires a 1µF ceramic input capacitor to GND.
3 VOUT power_out Regulated output voltage (3.3V for the -33 suffix). Delivers up to 150mA with 180mA current limit. Requires a 1µF ceramic output capacitor to GND.

CAD (KiCad official)

  • Symbol: BL8078CC3TR33
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: bl8078cc3tr33-etched.step / bl8078cc3tr33-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bl8078cc3tr33.step / bl8078cc3tr33.glb are the bare package body.

Provenance

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

  • Datasheet: BL Shanghai Belling datasheet (5 pp, sha256 85f4bbd4c457d3ba, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
