BL9110-330BPFB

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

BL9110-330BPFB 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 GND power_in Ground / device return. Reference for the internal bandgap, error amplifier and output pass FET; must be the low-impedance return for both input and output decoupling capacitors.
2 VOUT power_out Regulated 3.3V output pin, up to 1A load current. Requires a ≥2.2uF ceramic output capacitor to GND for stability; internal ~50Ω discharge resistor pulls VOUT down when the regulator is disabled.
3 VDD power_in Unregulated supply input, 2.5V to 6V absolute range (VOUT+VDROP minimum for regulation). Bypass with ≥2.2uF ceramic capacitor to GND close to the pin; also serves as the tab connection on SOT-223-3.

CAD (KiCad official)

  • Symbol: BL9110-330BPFB
  • Footprint: Package_TO_SOT_SMD:SOT-223-3_TabPin2
  • 3D model: SOT-223 (KiCad packages3D, STEP)
  • 3D model files: bl9110-330bpfb-etched.step / bl9110-330bpfb-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bl9110-330bpfb.step / bl9110-330bpfb.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
bl9110-330bpfb.step 64 KB You want the bare part, or you mark your own boards.
bl9110-330bpfb-etched.step 2.7 MB You want the part with BL9110-330BPFB already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 653 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.
