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 | Voltage input pin. Operating range 2V to 6V (absolute max 7V). Bypass to ground with at least a 1uF ceramic capacitor. |+| 2 | GND | power_in | Device ground reference return. |+| 3 | EN | input | Enable input, active high. VIH >= 1.4V enables the regulator; VIL <= 0.4V shuts it down (IQ drops to ~1uA). Absolute max VIN+0.3V. Do not leave floating. |+| 4 | NC | unconnected | No internal connection. Leave floating or tie to GND. |+| 5 | OUT | power_out | Regulated voltage output pin. Fixed 2.0V nominal, +/-2% accuracy, up to 300mA. Requires >=1uF ceramic bypass capacitor to GND for stability (stable with low-ESR ceramic). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SOT-25-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `AP7331-20WG-7W`+- `AP7331-20WG-7`+- `AP7331-20WG-7ADJ-W`+- `AP7331-20WG-7FDC`+- `AP7331-20WG-7FDC-7`+- `AP7331-20WG-7ADJ-DFN`++## CAD (KiCad official)++- Symbol: `AP7331-20WG-7`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-25-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](docs/ap7331-20wg-7-datasheet.pdf) (13 pp, sha256 `9fdedb2b73161d34`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
