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 (0V) for the regulator. Connect to the system ground plane; the input and output decoupling capacitors return here. |+| 2 | VIN | power_in | Unregulated input supply, up to 30V absolute maximum. Bypass with a 10µF capacitor (C1) to GND close to the pin per the application circuit. |+| 3 | VOUT | power_out | Regulated 3.3V output (±3%, tested at VIN=5.5V, IOUT=10mA). Rated 60mA typical / 100mA max output current; requires a 10µF (C2) output capacitor to GND for stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SOT-89 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `HT7133-1-1`+- `HT7133-1-A`++## CAD (KiCad official)++- Symbol: `HT7133-1`+- Footprint: `Package_TO_SOT_SMD:SOT-89-3`+- 3D model: SOT-89 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UMW datasheet](docs/ht7133-1-datasheet.pdf) (14 pp, sha256 `ae108c17cf1258c8`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
