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 reference for the regulator. On fixed-voltage AZ1117I versions (including the -3.3 variant) the ADJ pin is internally tied to the fixed feedback divider, so pin 1 functions as the device ground return. |+| 2 | VOUT | power_out | Regulated 3.3V output (1.176-1.224V… - for -3.3 variant: nominal 3.3V, ±1% accuracy over line/load). Requires a minimum 10µF output capacitor with ESR < 20Ω (low-ESR ceramic compatible). Pin 2 is internally connected to the SOT-223 tab. |+| 3 | VIN | power_in | Unregulated input supply. Recommended VIN ≤ 15V (absolute max 18V). Requires VIN ≥ VOUT + VDROP (typ. 1.2V @ 0.8A for SOT223) for regulation. A 10µF bypass capacitor is recommended near this pin. |+| 4 | VOUT | power_out | SOT-223 heat-spreader tab, internally connected to pin 2 (VOUT). Soldered to a copper pour on the PCB for heat dissipation (θJA drops from 125 to 100 °C/W with heatsink copper). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated AZ1117IH 3 3TRG1 |+| Package | SOT-223 |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++- `AZ1117IH-3.3TRG1`+- `AZ1117IH-3.3TRG1AZ1117ID-3.3TRG1`++## CAD (KiCad official)++- Symbol: `AZ1117IH-3.3TRG1`+- Footprint: `Package_TO_SOT_SMD:SOT-223-3_TabPin2`+- 3D model: SOT-223 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated AZ1117IH 3 3TRG1 datasheet](https://www.diodes.com/assets/Datasheets/AZ1117IH-3.3TRG1.pdf) (17 pp, sha256 `48934059d42aa84f`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
