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 | Ground reference. Common return for both input and output. Single-point GND is recommended per the application circuits. |+| 2 | VIN | power_in | Regulator input supply. Absolute maximum -0.3V to 28V; recommended operating range up to 24V. Bypass with a 10µF capacitor to GND as shown in the application circuits. |+| 3 | VOUT | power_out | Regulated 3.3V output (±5% tolerance, 3.135V to 3.465V at IOUT=10mA). Supplies up to 30mA. Requires a 10µF output capacitor to GND for stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | KEXIN |+| Package | SOT-89-3 |+| Category | PMIC |+| Pins | 3 |++## CAD (KiCad official)++- Symbol: `HT7133`+- 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:** [KEXIN datasheet](docs/ht7133-datasheet.pdf) (5 pp, sha256 `ce94186aa5a83426`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
