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 | Device ground reference. In DPAK this is the left lead and is electrically common with the exposed tab used as the primary heat-sinking surface. |+| 2 | OUTPUT | power_out | Regulated 3.3 V output (nominal 3.3 V, tolerance +/-2% at 25 degC; 3.234-3.366 V at Io = 50 mA). Supports up to 500 mA continuous with internal current limit around 1 A. Requires a >=2.2 uF (ESR 0.1-10 ohm) output capacitor for stability. |+| 3 | INPUT | power_in | Unregulated DC input supply, absolute maximum -0.5 V to 20 V. For 3.3 V operation Vi >= 4.3 V (Io = 0) or 4.6 V (Io = 500 mA) is required to stay out of dropout (Vd typ. 0.4 V at 500 mA). A 0.1 uF input bypass capacitor is recommended. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | DPAK |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `KF33BDT-TR`+- `KF33BDT-TRBD-TR`++## CAD (KiCad official)++- Symbol: `KF33BDT-TR`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: DPAK (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [STMicroelectronics datasheet](https://www.st.com/resource/en/datasheet/kf33bdt-tr.pdf) (21 pp, sha256 `a683c58723f09c6f`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
