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). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated AZ1117CR 3 3TRG1 |+| Package | SOT-89 |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++- `AZ1117CR-3.3TRG1R`+- `AZ1117CR-3.3TRG1R2`+- `AZ1117CR-3.3TRG1H`+- `AZ1117CR-3.3TRG1H2`+- `AZ1117CR-3.3TRG1D`+- `AZ1117CR-3.3TRG1TR3`++## CAD (KiCad official)++- Symbol: `AZ1117CR-3.3TRG1`+- Footprint: `Package_TO_SOT_SMD:SOT-89-3`+- 3D model: SOT-89 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated AZ1117CR 3 3TRG1 datasheet](https://www.diodes.com/assets/Datasheets/AZ1117CR-3.3TRG1.pdf) (24 pp, sha256 `8333717aa7b5f90f`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
