Diodes Incorporated AZ1117CR 3 3TRG1 · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89
AZ1117CR-3.3TRG1 from Diodes Incorporated AZ1117CR 3 3TRG1, in a SOT-89. 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 | Ground / regulator common return. On the fixed 3.3V version this pin (labeled ADJ/GND on the pinout diagram) is used as GND; the internal adjust divider is factory-trimmed to produce 3.3V. |
| 2 | OUTPUT | power_out | Regulated 3.3V output (±1%). Requires a minimum 10µF output capacitor with ESR <20Ω (low-ESR ceramic recommended). Current limit typ. 1.35A, dropout typ. 1.2V at 0.8A. |
| 3 | INPUT | power_in | Unregulated input supply, up to 15V recommended (18V absolute max). Bypass with a 10µF capacitor close to the pin. |
| 4 | VOUT | power_out | SOT-89 metal tab, electrically connected to the OUTPUT pin. Serves as the primary heat-dissipation path - solder to a copper pour for improved thermal performance (θJA ≈ 170°C/W without heatsink, 150°C/W with heatsink). |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 455 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.
