AIC1734-18GXATR from AIC Analog Integrations, 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 | Power ground return for the regulator. Common return for both input and output. |
| 2 | VIN | power_in | Unregulated power supply input. Absolute maximum 12V (min -0.3V); typical operating range 4.0V-12V (5.5V-12V for the 5.0V/5.2V versions). Bypass with a 1µF input capacitor. |
| 3 | VOUT | power_out | Regulated output pin. For AIC1734-18: 1.8V ±2% at up to 300mA. Requires a 1µF output capacitor for loop stability (aluminum electrolytic recommended; ceramic not suggested per Note 1). |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 472 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.
