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 supply, 2.5-5.5 V (absolute max 6.5 V). Bypass to GND with a 1 µF ceramic capacitor placed close to the pin. |+| 2 | GND | power_in | Device ground reference. Return path for input, output, and enable currents; tie directly to the system ground plane. |+| 3 | EN | input | Active-high enable. Drive ≥1.2 V (VENH) to enable the regulator, ≤0.4 V (VENL) to shut down (ISHDN < 1 µA). Input current ≤1 µA over 0-5.5 V; do not leave floating. |+| 4 | NC | unconnected | No internal connection. May be left floating or tied to GND for mechanical stability. |+| 5 | VOUT | power_out | Regulated 1.2 V output (WL2808E12-5 variant). Requires a 1 µF ceramic output capacitor to GND for stability; current-limited/short-circuit-protected via internal fold-back circuit. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | WILLSEMI Will Semicon |+| Package | SOT-23-5L |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `WL2808E12-5/TR`++## CAD (KiCad official)++- Symbol: `WL2808E12-5`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [WILLSEMI Will Semicon datasheet](docs/wl2808e12-5-datasheet.pdf) (9 pp, sha256 `332362e3f4478bf8`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
