S-817B33AMC-CWWT2U

ABLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

S-817B33AMC-CWWT2U from ABLIC, 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 VSS power_in Ground / GND pin. Common return for input and output.
2 VIN power_in Unregulated input voltage pin. Nominal operating range up to ~7 V; VIN must exceed VOUT by at least the dropout voltage (~160 mV typ. at IOUT=10 mA for the 5 V product).
3 VOUT power_out Regulated 3.3 V +/-2.0% output. Requires a ceramic output capacitor of 0.1 uF or more for stability. Deliverable current depends on VIN headroom (this variant has no built-in short-circuit protection).
4 NC unconnected No connection. Electrically open inside the package. May be left floating, or tied to VIN or VSS.
5 NC unconnected No connection. Electrically open inside the package. May be left floating, or tied to VIN or VSS.

CAD (KiCad official)

  • Symbol: S-817B33AMC-CWWT2U
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: s-817b33amc-cwwt2u-etched.step / s-817b33amc-cwwt2u-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); s-817b33amc-cwwt2u.step / s-817b33amc-cwwt2u.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
s-817b33amc-cwwt2u.step 85 KB You want the bare part, or you mark your own boards.
s-817b33amc-cwwt2u-etched.step 2.9 MB You want the part with S-817B33AMC-CWWT2U already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 711 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: ABLIC datasheet (50 pp, sha256 4f66023699c29ab1, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
