Connect to the common/single-point ground return of the regulator. |+| 2 | VIN | power_in | Unregulated supply input. Operating input range 4.75V to 40V (absolute maximum 45V). A 10µF input capacitor (C1) to GND is recommended. |+| 3 | VOUT | power_out | Regulated 5.0V output (±2% tolerance). Typical output current 100mA, short-circuit current ~180mA. A 10µF output capacitor (C2) to GND is required for stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Shanghai Siproin Microelectronics H7550 H |+| Package | SOT-23-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `H7550-H#T`+- `H7550-H#P`+- `H7550-H#M`++## CAD (KiCad official)++- Symbol: `H7550-H#`+- 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:** [Shanghai Siproin Microelectronics H7550 H datasheet](docs/h7550-h-datasheet.pdf) (11 pp, sha256 `942d23c6184c5e31`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
