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

BL8568GCB5ATR33 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 Supply voltage input. Recommended operating range 2.0V to 6V (absolute max 8V). A 1uF input capacitor is recommended close to this pin.
2 Vss power_in Ground / negative supply return for the regulator.
3 CE input Chip Enable. Drive high (Vceh ≥ 1.0V, up to Vin) to enable the regulator; drive low (Vcel ≤ 0.5V) to enter shutdown (~0.1uA). Internal ~500kΩ pull-down to Vss; when disabled an internal ~1.5kΩ discharge resistor pulls Vout to ground.
4 NC unconnected No internal connection. Leave floating or tie to Vss.
5 Vout power_out Regulated voltage output (3.3V fixed for BL8568GCB5ATR33 variant, ±2%). Rated for up to 500mA (300mA typical continuous). A 1uF output capacitor is recommended for stability.

Two STEP files. Same geometry, different body top:

File Size Use it when
bl8568gcb5atr33.step 85 KB You want the bare part, or you mark your own boards.
bl8568gcb5atr33-etched.step 3.3 MB You want the part with BL8568GCB5ATR33 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 765 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.

Provenance

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

  • Datasheet: BL Shanghai Belling datasheet (9 pp, sha256 d1708465be2899cb, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
