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 reference pin. All device voltages are specified with respect to this pin. |+| 2 | VOUT | power_out | Regulated 3.3V output pin. Delivers up to 150mA. Recommended output capacitor range is 1µF to 10µF for stability. |+| 3 | VIN | power_in | Regulator input supply pin. Accepts up to 36V (absolute max 40V). At least a 1µF supply bypass capacitor is recommended close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Jiangsu RUNIC Tech |+| Package | SOT-23-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `RS7533-1YF31YF3`+- `RS7533-1YF31YE3L`+- `RS7533-1YF31YE3`++## CAD (KiCad official)++- Symbol: `RS7533-1YF3`+- 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:** [Jiangsu RUNIC Tech datasheet](docs/rs7533-1yf3-datasheet.pdf) (11 pp, sha256 `818bd81e05d2139f`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
