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 supply input voltage. Recommended operating range 3.3V to 40V (absolute maximum -0.3V to 45V). A 1µF ceramic bypass capacitor to GND is recommended near the pin. |+| 2 | VOUT | power_out | Regulated 5.0V output (fixed, -50 variant). Delivers up to 150mA with typical dropout of 1000mV @ 100mA. Requires a 2.2µF low-ESR ceramic output capacitor to GND for stability. |+| 3 | GND | power_in | Device ground reference. Typical quiescent ground current is 2.5µA at no load and ~25µA at 100mA load. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `AP7381-50SA-750SA-7`+- `AP7381-50SA-728Y-13`+- `AP7381-50SA-733Y-13`+- `AP7381-50SA-750Y-13`+- `AP7381-50SA-770Y-13`+- `AP7381-50SA-733Y-TC`+- `AP7381-50SA-728V-A`+- `AP7381-50SA-733V-A`+- `AP7381-50SA-750V-A`+- `AP7381-50SA-770V-A`++## CAD (KiCad official)++- Symbol: `AP7381-50SA-7`+- Footprint: `Package_TO_SOT_SMD:SOT-23`+- 3D model: SOT-23 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](docs/ap7381-50sa-7-datasheet.pdf) (13 pp, sha256 `657d25b1f48ab5dc`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
