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 | VIN | power_in | Power input voltage. Operating range 2V to 6.5V (absolute max 7V). Decouple with a 1µF ceramic capacitor to GND placed as close as possible to the pin. |+| 2 | GND | power_in | Device ground. Return path for both input and output capacitors; route with wide, short copper trace back to this pin for best transient performance. |+| 3 | EN | input | Chip enable, active high, CMOS logic level (VIL ≤ 0.4V shutdown, VIH ≥ 1.2V enabled at VIN = 3-5.5V). High impedance input (IEN ≈ 1µA typ.); must not be left floating. Tie to VIN to keep the regulator always on. |+| 4 | NC | unconnected | No internal connection. Leave floating or tie to GND for board layout convenience. |+| 5 | VOUT | power_out | Regulated output voltage (1.2V nominal for the M12 variant), ±2% accuracy at IOUT = 40mA. Delivers up to 300mA (current-limit typ. 450mA). Requires ≥1µF ceramic output capacitor (X5R/X7R) placed close to the pin for stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | PJSEMI |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `PJ9193M12SE`+- `PJ9193M12SESA`+- `PJ9193M12SESC`+- `PJ9193M12SESQ`++## CAD (KiCad official)++- Symbol: `PJ9193M12SE`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [PJSEMI datasheet](docs/pj9193m12se-datasheet.pdf) (None pp, sha256 `9a82ee51ef372c12`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
