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 | Regulator input supply. Operating range 1.2 V to 6 V (absolute max 6 V). Requires ~10 uF ceramic input capacitor (Ci) to ground for stability. |+| 2 | VSS | power_in | Ground / return pin (接地端). Common ground reference for input, output, and CE. |+| 3 | CE | input | Chip Enable (使能端). Logic high (VCEH >= 1.6 V, up to VIN) enables the regulator; logic low (VCEL <= 0.5 V) disables it and drops supply current to ~1 uA. Input current <= 0.5 uA. Do not leave floating. |+| 4 | NC | unconnected | No internal connection (空). Leave floating or tie to any safe potential per board convention. |+| 5 | VOUT | power_out | Regulated output (输出端). Fixed 1.2 V ±2% for the -12 variant, delivering up to 300 mA (VIN=4.3 V). Requires ~10 uF ceramic output capacitor (Co) to ground; internal current limit and short-circuit protection. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MSKSEMI |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `RT9193-12GB-MS12GB-MS`+- `RT9193-12GB-MS15GB-MS`+- `RT9193-12GB-MS18GB-MS`+- `RT9193-12GB-MS25GB-M`+- `RT9193-12GB-MS28GB-MS`+- `RT9193-12GB-MS30GB-MS`+- `RT9193-12GB-MS33GB-MS`++## CAD (KiCad official)++- Symbol: `RT9193-12GB-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/rt9193-12gb-ms-datasheet.pdf) (8 pp, sha256 `f30db9087e2ca5f2`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
