AZ1117H-ADJTRE1 from Diodes Incorporated, 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 | ADJ/GND | input | Adjust pin for the adjustable version (AZ1117-ADJ); connect to the R1/R2 feedback divider to set VOUT = VREF*(1+R2/R1)+IADJ*R2, where VREF=1.25V and IADJ typ 60 uA. Serves as GND on fixed-output variants. |
| 2 | OUTPUT | power_out | Regulated output; delivers up to 1A. Requires >=22 uF output capacitor for stability. On SOT-223 the output pin is electrically connected to the tab (VOUT). |
| 3 | INPUT | power_in | Unregulated input supply; VIN(max) = 20V absolute, 15V recommended. Requires >=10 uF input capacitor. Dropout is 1.15V typical at 1A. |
| 4 | VOUT (TAB) | power_out | Metal tab of the SOT-223 package, internally connected to OUTPUT (pin 2). Also serves as the primary thermal path (theta_JA = 120 C/W, theta_JC = 25 C/W); solder to a copper pour tied to VOUT. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 456 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.
