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. Operating range 3.5 V to 15 V (absolute max 18 V). Decouple with a 1 µF input capacitor to GND close to the pin. |+| 2 | GND | power_in | Ground / common return (Vss). Connect to system ground. |+| 3 | CE | input | Chip enable input, active high. Drive high to enable the regulator; typically pulled up through ~10 kΩ per the application circuit. Available only on the SOT-23-5 variant. |+| 4 | NC | unconnected | Not connected. Leave floating or tie to a copper island; no internal connection on the SOT-23-5 package. |+| 5 | VOUT | power_out | Regulated 3.3 V output (±2% accuracy), rated for >400 mA. Decouple with a 1 µF output capacitor to GND close to the pin for stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Shanghai Siproin Microelectronics |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `H7233-1M5R1M5R`+- `H7233-1M5R1M5G`+- `H7233-1M5RH72XX-1M5X`+- `H7233-1M5R1PX`+- `H7233-1M5R1PR`+- `H7233-1M5R1PG`+- `H7233-1M5R1MX`+- `H7233-1M5R1MR`+- `H7233-1M5R1MG`++## CAD (KiCad official)++- Symbol: `H7233-1M5R`+- 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/h7233-1m5r-datasheet.pdf) (11 pp, sha256 `a21c635cc1616868`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
