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 both input and output. Reference for the internal bandgap and feedback network. |+| 2 | VIN | power_in | Unregulated supply input. Absolute max 18V; recommended operating range up to 15V (H7533-1 line-regulation window 4.5V ≤ VIN ≤ 16V). Bypass close to the pin with a small ceramic capacitor. |+| 3 | VOUT | power_out | Regulated 3.3V output (3.234V - 3.366V, ±2%). Sources up to 150mA typical. Requires an output capacitor for stability; low-ESR ceramic recommended. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Shanghai Siproin Microelectronics |+| Package | SOT-89-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `H7533-1PR`+- `H7533-1PG`+- `H7533-1TR`+- `H7533-1TG`+- `H7533-1NR`+- `H7533-1NG`++## CAD (KiCad official)++- Symbol: `H7533-1`+- Footprint: `Package_TO_SOT_SMD:SOT-89-3`+- 3D model: SOT-89-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Shanghai Siproin Microelectronics datasheet](docs/h7533-1-datasheet.pdf) (12 pp, sha256 `68d89a2084487dc3`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
