SSP7985P33PR

Shanghai Siproin Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

SSP7985P33PR from Shanghai Siproin Microelectronics, in a SOT-89-3. 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 directly to the system ground plane; return path for both the regulator quiescent current and the output load current.
2 VIN power_in Unregulated supply input. Operating range 5V to 60V (80V absolute maximum). A 1 uF input decoupling capacitor to GND is recommended near the pin.
3 VOUT power_out Regulated 3.3V output (±2%). Supplies up to 150mA with an internal current limit of ~250mA. Requires a 10 uF ceramic output capacitor to GND for stability and load-transient response.

  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: ssp7985p33pr-etched.step / ssp7985p33pr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ssp7985p33pr.step / ssp7985p33pr.glb are the bare package body.

Provenance

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

  • Datasheet: Shanghai Siproin Microelectronics datasheet (7 pp, sha256 222dc505d32d3079, 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).
