SSP7615-12MR from Shanghai Siproin Microelectronics, in a SOT-23-3. 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 Device ground reference. Connect to system ground close to the input and output bypass capacitor return paths for lowest noise and best regulation.
2 VOUT power_out Regulated output voltage pin. Fixed to 1.2 V on the -12MR option (1.2-5.0 V family, 0.1 V step); supplies up to 400 mA. Requires a 1 µF (ceramic or tantalum) output capacitor to GND close to the pin for loop stability and transient response.
3 VIN power_in Unregulated input supply pin, 1.5 V to 8 V operating range (absolute max −0.3 to 8 V). Bypass with a 1 µF low-ESR ceramic capacitor to GND close to the pin. In the SOT-23-3 variant the device is always enabled (no separate EN pin).

Two STEP files. Same geometry, different body top:

File Size Use it when
ssp7615-12mr.step 59 KB You want the bare part, or you mark your own boards.
ssp7615-12mr-etched.step 2.0 MB You want the part with SSP7615-12MR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 492 faces against 69 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 (13 pp, sha256 5ca4f994acdfaaba, 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).
