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. |

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.
