SSP1117-1.5V

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

SSP1117-1.5V 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. Tied to the tab in fixed-output versions of the SSP1117 family; carries the full load return current.
2 VOUT power_out Regulated 1.5V output, up to 1A load current. Requires a 10uF tantalum output capacitor for stability.
3 VIN power_in Unregulated input supply, 20V maximum. Requires at least VOUT + 1.3V dropout to regulate at 1A. Recommend a 10uF tantalum bypass capacitor to ground.
4 VOUT power_out SOT-223 tab, electrically connected to VOUT. Provides the primary thermal path to the PCB copper for heat dissipation.

Two STEP files. Same geometry, different body top:

File Size Use it when
ssp1117-1-5v.step 64 KB You want the bare part, or you mark your own boards.
ssp1117-1-5v-etched.step 1.6 MB You want the part with SSP1117-1.5V already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 424 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 4c5a7e0e0fbea4b3, 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).
