SSP1117-3.3V from Shanghai, in a SOT-223-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ADJ/GND | input | Ground return for the regulator. On the fixed-output SSP1117-3.3V this pin is the device ground reference; on the ADJ variant the same pin becomes the ADJ feedback node. |
| 2 | VOUT | power_out | Regulated 3.3V output. Sources up to 1A load current. Requires a 10uF tantalum output capacitor for stability. |
| 3 | VIN | power_in | Unregulated input supply. Recommended maximum 20V, absolute max 30V. For the 3.3V output, minimum operating Vin is 4.8V with a 10uF tantalum bypass capacitor recommended. |
