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 +5.0 V output pin (4.75 V to 5.25 V over line/load). Delivers up to 100 mA; a 0.1 µF output bypass capacitor is recommended to improve transient response. |+| 2 | GND | power_in | Ground reference. Common ground between input and output is required. Multiple GND pins are tied together internally and also aid in heat dissipation through the leads. |+| 3 | GND | power_in | Ground reference (bussed with pins 2, 6, 7). Provides return path for quiescent and load current. |+| 4 | NC | unconnected | No internal connection. Leave floating or tie to GND per board convention. |+| 5 | NC | unconnected | No internal connection. Leave floating or tie to GND per board convention. |+| 6 | GND | power_in | Ground reference (bussed with pins 2, 3, 7). |+| 7 | GND | power_in | Ground reference (bussed with pins 2, 3, 6). |+| 8 | VIN | power_in | Unregulated input supply pin. Recommended operating range 7.0 V to 20 V (absolute max 30 Vdc); must remain ~2 V above VOUT for regulation. A 0.33 µF input bypass capacitor is recommended when placed away from the supply filter. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | XINLUDA |+| Package | SOP-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `XL78L05A`+- `XL78L05AXT78L05`++## CAD (KiCad official)++- Symbol: `XL78L05A`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [XINLUDA datasheet](docs/xl78l05a-datasheet.pdf) (9 pp, sha256 `4e962ee571afc5f3`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
