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. Connect to system ground; place input and output decoupling caps' return leads close to this pin. |+| 2 | VIN | power_in | Unregulated supply input, -0.3V to +18V absolute max. Recommended operating VIN ≥ 4.3V for 3.3V output with 40mA load. Bypass to GND with a capacitor placed close to the pin. |+| 3 | VOUT | power_out | Regulated 3.3V ±2% output (3.201-3.399V). Sources up to 250mA. Requires an output capacitor >2.2µF to GND (tantalum recommended) for loop stability via ESR-based compensation. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HXY MOSFET |+| Package | SOT-89 |+| Category | PMIC |+| Pins | 3 |++## CAD (KiCad official)++- Symbol: `HT7333-1`+- 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:** [HXY MOSFET datasheet](docs/ht7333-1-datasheet.pdf) (10 pp, sha256 `c470ac791b0886ce`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
