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 | Ground / common return for the regulator. Bond the input and output capacitor grounds back to this pin with wide, short traces (single-point GND). |+| 2 | VOUT | power_out | Regulated output voltage pin. Fixed 5.0V (±2%) for the -50 option, delivering up to 100mA. Requires a ≥10µF X7R/X5R ceramic capacitor to GND placed close to the pin for stability. |+| 3 | VIN | power_in | Unregulated supply input, absolute max 36V (-0.3 to +36V). Requires a 10µF ceramic decoupling capacitor to GND close to the pin. Dropout ≈25mV typ at 1mA for 5V option. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | PJSEMI |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `PJ75AL50SASA`+- `PJ75AL50SASC`+- `PJ75AL50SASQ`+- `PJ75AL50SASE`++## CAD (KiCad official)++- Symbol: `PJ75AL50SA`+- 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:** [PJSEMI datasheet](docs/pj75al50sa-datasheet.pdf) (9 pp, sha256 `ec9ac50694a28a8f`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
