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 3.3V regulator (this pin becomes ADJ on the -ADJ adjustable variant). Ties the internal reference and error-amplifier return to system ground; carries the quiescent current (~5 mA typ, 10 mA max). |+| 2 | OUTPUT | power_out | Regulated 3.3V output (VOUT = 3.3V nominal, 1A max continuous). Requires a 22µF (tantalum recommended) or larger output capacitor for stability and to meet the PSRR/dropout specs. Internally current-limited to ~1.35A typ; thermal shutdown activates at TJ ≈ +150°C. |+| 3 | INPUT | power_in | Unregulated DC input, VIN. Recommended operating range up to 15V (absolute maximum 20V). Must be at least VOUT + VDROP (≥ ~4.45V at 1A load for the 3.3V version). A 10µF input bypass capacitor to GND is recommended near the pin. |+| TAB | OUTPUT (Tab) | power_out | Exposed metal heat-sink tab on the back of the TO-252 package, electrically common with pin 2 (OUTPUT). Solder to a copper pour tied to VOUT for thermal dissipation; θJC ≈ 17 °C/W for TO252-2. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes |+| Package | TO-252-2 |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++- `AZ1117D-3.3TRE1`+- `AZ1117D-3.3TRE1AZ1117H-3.3TRE1`+- `AZ1117D-3.3TRE1AZ1117R-3.3TRE1`+- `AZ1117D-3.3TRE1AZ1117T-3.3E1`+- `AZ1117D-3.3TRE1AZ1117S-3.3TRE1`++## CAD (KiCad official)++- Symbol: `AZ1117D-3.3TRE1`+- 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 datasheet](https://www.diodes.com/assets/Datasheets/AZ1117D-3.3TRE1.pdf) (32 pp, sha256 `a54ad8d300c88315`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
