AZ1117CH2-5.0TRG1 from Diodes Incorporated AZ1117CH2 5 0TRG1, in a SOT-223. 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 | INPUT | power_in | Unregulated input supply. Absolute max 18 V; recommended operating max 15 V. Requires a 10 µF (or larger) bypass capacitor to GND close to the pin for stability. |
| 2 | ADJ/GND | power_in | Ground reference on the fixed-voltage AZ1117C-5.0 version (ADJ pin is internally tied to GND on fixed variants). Serves as the return for both the input bypass and output capacitors. |
| 3 | OUTPUT | power_out | Regulated 5.0 V output (±1% at 25 °C, ±2% over -20 to +125 °C). Current limit 1.35 A typ. Requires a minimum 22 µF (ESR < 20 Ω) ceramic output capacitor for stability. |
| 4 | ADJ/GND | power_in | SOT-223 thermal tab, electrically connected to the ADJ/GND pin. On fixed 5.0 V version this is GND; solder to a copper pour to improve θJA (≈125 °C/W without heatsink, 100 °C/W with heatsink for SOT223). |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 584 faces against 75 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.
