BL8075CB5TR50

BL Shanghai Belling · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

BL8075CB5TR50 from BL Shanghai Belling, in a SOT-23-5. 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 VIN power_in Regulator input supply. Operating range 3 V to 16 V (absolute max 20 V). Bypass to GND with a 1 uF ceramic capacitor close to the pin.
2 GND power_in Device ground reference for the internal reference, error amplifier, and output driver.
3 EN input Active-high enable input. VEN >= 1.5 V (up to VIN) turns the regulator on; VEN <= 0.4 V shuts it down (Iq typ. 1 uA at Vin=12 V, VEN=0 V). Do not leave floating.
4 NC unconnected No internal connection. Leave floating or tie to GND per PCB convention.
5 VOUT power_out Regulated output. Factory-trimmed to 5.0 V (suffix 50) at ±2% accuracy, up to 500 mA. Requires a 1 uF ceramic output capacitor to GND for stability.

CAD (KiCad official)

  • Symbol: BL8075CB5TR50
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: bl8075cb5tr50-etched.step / bl8075cb5tr50-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bl8075cb5tr50.step / bl8075cb5tr50.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
bl8075cb5tr50.step 85 KB You want the bare part, or you mark your own boards.
bl8075cb5tr50-etched.step 2.7 MB You want the part with BL8075CB5TR50 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 631 faces against 102 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.
