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 | Supply voltage input. Accepts up to 35V absolute maximum; must be at least ~2V above VOUT (dropout ~2V typ at 100mA) for regulation. Bypass with a 0.33uF capacitor near the pin. |+| 2 | GND | power_in | Ground/common reference. Must share a common ground between the input and output. Also connected to the exposed tab of the TO-252 package for thermal dissipation. |+| 3 | VOUT | power_out | Regulated 5.0V output (+/-5% tolerance, +/-3.6% at Io=40mA/VIN=10V). Delivers up to 500mA. A 0.1uF output capacitor is recommended to improve transient response (not required for stability). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Shanghai Siproin Microelectronics |+| Package | TO-252 |+| Category | PMIC |+| Pins | 3 |++## CAD (KiCad official)++- Symbol: `SSP78M05`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: TO-252 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Shanghai Siproin Microelectronics datasheet](docs/ssp78m05-datasheet.pdf) (9 pp, sha256 `627f931f79029278`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
