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 pin. Absolute maximum supply voltage -0.3V to 8V. Recommended input capacitor CIN=10uF close to the pin for stable operation. |+| 2 | GND | power_in | Ground/VSS reference for the regulator. Keep resistance low between VIN and VSS wiring. |+| 3 | CE | input | Chip Enable pin. CMOS hysteresis inverter input; drive to VIN to enable and to VSS to shut down (standby current ~0.1uA). Should be tied to a valid VIN or VSS level, not left floating. |+| 4 | NC | unconnected | No Connection. Leave open or tie to ground; not internally bonded. |+| 5 | VOUT | power_out | Regulated output pin. Fixed 1.2V (±2%) for the -B122 option, up to 350mA typical output current. Requires an output capacitor CL≥10uF placed close to VOUT/GND for phase compensation stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MSKSEMI |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `XC6219B122MR-MS`+- `XC6219B122MR-MSPR-MS`++## CAD (KiCad official)++- Symbol: `XC6219B122MR-MS`+- 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:** [MSKSEMI datasheet](docs/xc6219b122mr-ms-datasheet.pdf) (9 pp, sha256 `1fa6ceb7187b3251`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
