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 | Device ground / common return for the internal reference, error amplifier, and pass FET. Tie to the system ground plane; place the input and output capacitor returns close to this pin to minimize regulation error. |+| 2 | VIN | power_in | Unregulated input supply. Operating range up to 15 V (absolute max 18 V). For the H7133-1 (3.3 V output) line regulation is specified over 4.5 V ≤ VIN ≤ 16 V. Decouple with a ceramic/electrolytic capacitor (typ. 10 µF) to GND close to the pin. |+| 3 | VOUT | power_out | Regulated 3.3 V output (3.234 V min / 3.300 V typ / 3.366 V max at IOUT=10 mA). Supplies up to 50 mA. Requires an output capacitor (typ. 10 µF) to GND for stability. Dropout ≈ 30 mV at 1 mA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Shanghai Siproin Microelectronics |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `H7133-1TR`+- `H7133-1TG`+- `H7133-1PR`+- `H7133-1PG`+- `H7133-1NR`+- `H7133-1NG`++## CAD (KiCad official)++- Symbol: `H7133-1`+- Footprint: `Package_TO_SOT_SMD:SOT-23`+- 3D model: SOT-23 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Shanghai Siproin Microelectronics datasheet](docs/h7133-1-datasheet.pdf) (16 pp, sha256 `b56d63e4e3666e63`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
