BL8078CC3BTR50

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

BL8078CC3BTR50 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 VOUT power_out Regulated output voltage (5.0V for -50 suffix, ±2%). Requires a 1uF ceramic output capacitor to GND for stability. Maximum output current 150mA; internally current-limited at ~180mA.
2 GND power_in Device ground reference. Should be tied to the ground plane; also the thermal path for the SOT-89 tab (pin 2 is fused to the mounting tab).
3 VIN power_in Unregulated supply input, 3V to 40V (50V absolute max). Requires a 1uF ceramic input capacitor to GND close to the pin.

CAD (KiCad official)

  • Symbol: BL8078CC3BTR50
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: bl8078cc3btr50-etched.step / bl8078cc3btr50-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bl8078cc3btr50.step / bl8078cc3btr50.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
bl8078cc3btr50.step 57 KB You want the bare part, or you mark your own boards.
bl8078cc3btr50-etched.step 2.3 MB You want the part with BL8078CC3BTR50 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 574 faces against 42 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.
