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 | VIN | power_in | Unregulated input voltage. Operating range 4.5 V to 45 V; withstands transients from -42 V to +45 V. A 100 nF input capacitor is recommended. |+| 2 | GND | power_in | Ground; substrate connection. Tied internally to the TAB. |+| 3 | VOUT | power_out | Regulated output voltage; collector of the internal PNP pass transistor. Fixed 5.0 V ±2.0% at up to 100 mA. Requires a stability output capacitor of ≥10 µF (5.0 V version) with ESR within the specified stability window. |+| TAB | GND | power_in | Ground; substrate and best thermal connection to the die. Solder to a copper pour for effective heat dissipation (θJA ~99 °C/W with 1 oz, 100 mm² copper). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOT-223-3 |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++- `NCV4264-2ST50T3GST50T3G`+- `NCV4264-2ST50T3GST33T3G`+- `NCV4264-2ST50T3GD`++## CAD (KiCad official)++- Symbol: `NCV4264-2ST50T3G`+- Footprint: `Package_TO_SOT_SMD:SOT-223-3_TabPin2`+- 3D model: SOT-223-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [onsemi datasheet](https://www.onsemi.com/pdf/datasheet/ncv4264-2st50t3-d.pdf) (11 pp, sha256 `46d2bf0aebb126d7`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
