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 fixed-output AZ1117I-3.3 version, pin 1 is the GND (adjust) pin connected internally to the trimmed reference divider. Return current for both quiescent (I_Q ≈ 6mA max) and load current flows through this pin. |+| 2 | VOUT | power_out | Regulated 3.3V output (Typ 3.3V, ±1% initial accuracy, ±1.5% over temperature). Rated for ≥1A load current with 1.35A typical current limit. Requires a minimum 10µF low-ESR (<20Ω) ceramic capacitor to ground for stability. |+| 3 | VIN | power_in | Unregulated input supply. Recommended operating range is up to 15V; absolute maximum is 18V. For 3.3V output, V_IN must exceed V_OUT by the dropout voltage (typ 1.3V, max 1.4V on TO252-2 at I_OUT = 0.8A). Bypass with ≥10µF capacitor to ground. |+| TAB | VOUT | power_out | Exposed thermal tab, electrically connected to VOUT (pin 2). Provides the primary heat conduction path to the PCB copper - thermal resistance θ_JA drops from 100°C/W (no heatsink) to 70°C/W (soldered to 100mm² 2oz copper, 8×0.5mm vias). Solder to a copper pour that is also the V_OUT net. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated AZ1117ID 3 3TRG1 |+| Package | TO-252-2 |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++- `AZ1117ID-3.3TRG1`+- `AZ1117ID-3.3TRG1`+- `AZ1117ID-3.3TRG1AZ1117IH-3.3TRG1`++## CAD (KiCad official)++- Symbol: `AZ1117ID-3.3TRG1`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: TO-252-2 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated AZ1117ID 3 3TRG1 datasheet](docs/az1117id-3-3trg1-datasheet.pdf) (17 pp, sha256 `48934059d42aa84f`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
