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 return. All voltages (VIN, VOUT) are referenced to this pin. |+| 3 | VIN | power_in | Unregulated supply input. Absolute max 15 V (recommended operating up to 12 V). For 3.0 V output, VIN must be ≥ ~4 V (dropout ~100 mV at 40 mA). A small input decoupling capacitor to GND is recommended. |+| 2 | VOUT | power_out | Regulated 3.0 V output (±3% tolerance, 2.91-3.09 V). Delivers up to 450 mA. An output capacitor to GND is required for stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SOT-89-3 |+| Category | PMIC |+| Pins | 3 |++## CAD (KiCad official)++- Symbol: `HT7830-A`+- 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:** [UMW datasheet](docs/ht7830-a-datasheet.pdf) (12 pp, sha256 `0ddd2116b6d87a09`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
