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 | Unregulated positive supply input. Operating range 3.5V to 15V (abs max 18V). Decouple with a 1uF capacitor from VIN to GND close to the pin. |+| 2 | GND | power_in | Ground reference return for both the input and regulated output. Must be tied to system ground. |+| 3 | CE | input | Chip Enable input. Drive high to enable the regulator; drive low to place the device in shutdown. Should not be left floating. |+| 4 | NC | unconnected | No internal connection. Leave floating or tie to any convenient net; typically left open. |+| 5 | VOUT | power_out | Regulated 3.3V output (tolerance +/-2%), rated for up to 500mA. Decouple with a 1uF tantalum or 6.8uF ceramic capacitor to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Shanghai Siproin Microelectronics |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `SSP7603P33M5RM5R`+- `SSP7603P33M5RM5G`+- `SSP7603P33M5RPR`+- `SSP7603P33M5RPG`+- `SSP7603P33M5RMR`+- `SSP7603P33M5RMG`++## CAD (KiCad official)++- Symbol: `SSP7603P33M5R`+- 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:** [Shanghai Siproin Microelectronics datasheet](docs/ssp7603p33m5r-datasheet.pdf) (9 pp, sha256 `3b68c21dd6651bc3`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
