SSP1117-5.0V

Shanghai Siproin Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

SSP1117-5.0V from Shanghai Siproin Microelectronics, 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 reference for the regulator. On fixed-voltage versions (including SSP1117-5.0V) pin 1 is the GND return; on the ADJ variant this same pin serves as the ADJ feedback node.
2 VOUT power_out Regulated 5.0V output (typ, ±2%). Delivers up to 1A load current. Requires a ~10uF tantalum output capacitor for stability.
3 VIN power_in Unregulated input supply. Recommended max 20V (absolute max 30V). For 5.0V output, Vin must exceed Vout by the dropout voltage (~1.3V at 1A). Recommended 10uF tantalum bypass capacitor to GND.
4 TAB power_in SOT-223 heat-sink tab (Fin), internally connected to VOUT (pin 2). Solder to a large copper pour to reduce thermal resistance (~20°C/W with minimal copper).

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ssp1117-5-0v.step 64 KB You want the bare part, or you mark your own boards.
ssp1117-5-0v-etched.step 1.8 MB You want the part with SSP1117-5.0V already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 454 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.

Provenance

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

  • Datasheet: Shanghai Siproin Microelectronics datasheet (9 pp, sha256 4548d0eb79d83846, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
