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 | OUT | power_out | Regulated 5V output. Typical VO = 5.0 V (4.75 V to 5.25 V over IO = 1 mA to 100 mA). Requires a 0.1 µF output decoupling capacitor to ground for stability. |+| 2 | GND | power_in | Ground / common return for the regulator. On SOT-89 this pin is also the large center tab used as the thermal/heat-sinking pad. |+| 3 | IN | power_in | Unregulated input voltage, up to 35 V absolute maximum. Requires a 0.33 µF input capacitor to ground close to the pin as recommended by the application circuit. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | PJSEMI |+| Package | SOT-89-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `PJ78L05SQ-N`++## CAD (KiCad official)++- Symbol: `PJ78L05SQ-N`+- Footprint: `Package_TO_SOT_SMD:SOT-89-3`+- 3D model: SOT-89-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [PJSEMI datasheet](docs/pj78l05sq-n-datasheet.pdf) (3 pp, sha256 `e0da4f4bfedb7582`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
