SSP7785-5.0V 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. High-voltage isolation pin (referenced as HV pin no.1 in ESD spec, so must remain floating for clearance to the input node). |
| 2 | GND | power_in | Ground connection. Return for input and output decoupling capacitors. |
| 3 | VOUT | power_out | Regulated 5.0 V output (±5% over line/load/temperature), 10 mA guaranteed output current. Requires a 22 µF or larger MLCC capacitor from VOUT to GND for stability. |
| 4 | NC | unconnected | Not connected. |
| 5 | NC | unconnected | Not connected. |
| 6 | NC | unconnected | Not connected. |
| 7 | VIN | power_in | High-voltage supply input, 50 V to 450 V DC operating range (absolute max 650 V). Requires a 2.2 µF capacitor from VIN to GND placed close to the pin. |
| 8 | NC | unconnected | Not connected. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 508 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.
