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 | VOUT | power_out | Regulated +3.3 V output. Delivers up to 100 mA with internal current limiting and thermal shutdown protection. Recommended output capacitor CO = 0.1 µF for stability. |+| 2 | GND | power_in | Common ground reference for the regulator. In SOT-89 this pin is the center lead and is also connected to the die-attach tab used for heat-sinking. |+| 3 | VIN | power_in | Unregulated DC input voltage. Absolute maximum 30 V for the 3.3-9 V output variants. Recommended input capacitor CI = 0.33 µF placed close to the pin if the device is far from the bulk supply filter. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | SOT-89-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `L78L33ACUTRACUTR`+- `L78L33ACUTRACZ`+- `L78L33ACUTRACZ-AP`+- `L78L33ACUTRABZ-AP`+- `L78L33ACUTRABD-TR`+- `L78L33ACUTRACD13TR`++## CAD (KiCad official)++- Symbol: `L78L33ACUTR`+- Footprint: `Package_TO_SOT_SMD:SOT-89-3`+- 3D model: SOT-89-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [STMicroelectronics datasheet](docs/l78l33acutr-datasheet.pdf) (47 pp, sha256 `385835a89181b63c`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
