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 | VOUT | power_out | Regulated output voltage. Fixed 5.0V nominal on the -50 option, ±2% accuracy. Requires a >=2.2µF low-ESR ceramic capacitor to GND for stability; supplies up to 150mA (current-limited). |+| 2 | GND | power_in | Device ground and return for the internal reference/error amplifier. Ground current is typically 2.5µA at no load and ~25µA at 100mA load. |+| 3 | VIN | power_in | Unregulated supply input. Recommended operating range 3.3V to 40V (absolute max 45V). Bypass with a >=1µF ceramic capacitor close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SOT-89 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `AP7381-50Y-13`+- `AP7381-50Y-1350SA-7`+- `AP7381-50Y-1350V-A`++## CAD (KiCad official)++- Symbol: `AP7381-50Y-13`+- Footprint: `Package_TO_SOT_SMD:SOT-89-3`+- 3D model: SOT-89 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](https://www.diodes.com/assets/Datasheets/AP7381-50Y-13.pdf) (None pp, sha256 `657d25b1f48ab5dc`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
