Shanghai Siproin Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · ESOP-8

SSP7785-3.3V from Shanghai Siproin Microelectronics, in a ESOP-8. 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 NC unconnected Not connected. Datasheet notes this pin is the high-voltage (HV) pin position (ESD HBM 2 kV applies to all pins except HV pin 1); leave floating.
2 GND power_in Ground connection. Reference for VIN and VOUT decoupling capacitors.
3 VOUT power_out Regulated output, 3.3 V nominal (±5%), up to 10 mA. Connect a 22 µF or larger MLCC capacitor from VOUT to GND for stability.
4 NC unconnected Not connected. Leave floating.
5 NC unconnected Not connected. Leave floating.
6 NC unconnected Not connected. Leave floating.
7 VIN power_in Supply voltage input. Accepts 50 V to 450 V DC (or 85-260 VAC via half-wave rectifier). Connect a 2.2 µF capacitor from VIN to GND.
8 NC unconnected Not connected. Leave floating.

CAD (KiCad official)

  • Symbol: SSP7785-3.3V
  • Footprint: Package_SO:SOIC-8-1EP_3.9x4.9mm_P1.27mm_EP2.41x3.3mm
  • 3D model: ESOP-8 (KiCad packages3D, STEP)
  • 3D model files: ssp7785-3-3v-etched.step / ssp7785-3-3v-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ssp7785-3-3v.step / ssp7785-3-3v.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ssp7785-3-3v.step 193 KB You want the bare part, or you mark your own boards.
ssp7785-3-3v-etched.step 2.2 MB You want the part with SSP7785-3.3V already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 528 faces against 63 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 (8 pp, sha256 6f98670f493b5efc, 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).
