TPMCP1702T-3302E from TECH PUBLIC, 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. Common return for input, output, and internal control circuitry. |
| 2 | VOUT | power_out | Regulated 3.3V output (3.201V min / 3.300V typ / 3.399V max at Iout=40mA). Delivers up to 300mA. Requires a ~10uF ceramic output capacitor for stability and load-transient response. |
| 3 | VIN | power_in | Unregulated supply input. Recommended operating range VOUT+2V to 22V; absolute max 22V; up to 18V per Electrical Characteristics. A ~10uF ceramic bulk capacitor to GND is recommended close to the pin. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 505 faces against 42 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.
