SSP78M05

Shanghai Siproin Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252

SSP78M05 from Shanghai Siproin Microelectronics, in a TO-252. 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. Accepts up to 35V absolute maximum; must be at least ~2V above VOUT (dropout ~2V typ at 100mA) for regulation. Bypass with a 0.33uF capacitor near the pin.
2 GND power_in Ground/common reference. Must share a common ground between the input and output. Also connected to the exposed tab of the TO-252 package for thermal dissipation.
3 VOUT power_out Regulated 5.0V output (+/-5% tolerance, +/-3.6% at Io=40mA/VIN=10V). Delivers up to 500mA. A 0.1uF output capacitor is recommended to improve transient response (not required for stability).

CAD (KiCad official)

  • Symbol: SSP78M05
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: ssp78m05-etched.step / ssp78m05-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ssp78m05.step / ssp78m05.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ssp78m05.step 119 KB You want the bare part, or you mark your own boards.
ssp78m05-etched.step 1.8 MB You want the part with SSP78M05 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 455 faces against 83 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 627f931f79029278, 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).
