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 | IN | power_in | Supply input pin, 1.9 V to 5.5 V. Must be closely decoupled to GND with a 1 µF or greater ceramic capacitor. |+| 2 | GND | power_in | Ground reference for the regulator. |+| 3 | EN | input | Enable control input, active high. VIH >= 1 V enables the output; VIL <= 0.4 V disables it. Internally pulled low by a 1 MΩ resistor to GND; do not leave floating. Tie to IN for always-on operation. |+| 4 | NC | unconnected | No connection. Leave floating or tie to a convenient net; no internal bond. |+| 5 | OUT | power_out | Regulated output pin, 3.3 V fixed (S5-33 option), up to 300 mA. Bypass with a 1 µF ceramic capacitor (X7R/X5R, ESR 5 mΩ to 500 mΩ) to GND. Internal 60 Ω auto-discharge to GND when EN is low. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Suntek |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `SK6011S5-33SK6011S5-XX`+- `SK6011S5-33SK6011UD4-XX`+- `SK6011S5-33SK6011D4-XX`++## CAD (KiCad official)++- Symbol: `SK6011S5-33`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Suntek datasheet](docs/sk6011s5-33-datasheet.pdf) (10 pp, sha256 `092617e8e32c9b09`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
