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 | GND | power_in | Device ground reference. Common return for input and output capacitors; connect to the single-point ground plane with a wide, short trace back to CIN and COUT. |+| 2 | VOUT | power_out | Regulated output voltage (3.0V ±2% for the -30 option), 300mA max. Requires a ≥1μF ceramic (X7R/X5R) capacitor to GND placed as close as possible for stability. Short-circuit protected at ~250mA and current-limited at ~530mA. |+| 3 | VIN | power_in | Unregulated supply input, up to +20V absolute maximum (+22V abs. max.). Bypass with a ≥1μF ceramic capacitor to GND, placed as close as possible to the pin to decouple supply glitches. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | PJSEMI |+| Package | SOT-23-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `PJ73AL30SCSC`+- `PJ73AL30SCSA`+- `PJ73AL30SCSQ`+- `PJ73AL30SCSE`++## CAD (KiCad official)++- Symbol: `PJ73AL30SC`+- Footprint: `Package_TO_SOT_SMD:SOT-23-3`+- 3D model: SOT-23-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [PJSEMI datasheet](docs/pj73al30sc-datasheet.pdf) (9 pp, sha256 `594527d1f30258ee`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
