Connect to system ground; also serves as the return for the internal reference and control loop. |+| 2 | VIN | power_in | Unregulated input supply, up to 30V absolute maximum. Bypass with a 10µF capacitor to GND close to the pin (per application circuit). |+| 3 | VOUT | power_out | Regulated 5.0V output (±3%), up to 100mA. Requires a 10µF output capacitor to GND for stability (per application circuit). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW Youtai Semiconductor Co Ltd |+| Package | SOT-89 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `HT7550-1SOT-89`+- `HT7550-1TO-92`+- `HT7550-1TO 92`+- `HT7550-1SOT23-3`+- `HT7550-1SOT-23`+- `HT7550-1SOT23-5`+- `HT7550-1SOT-23-5`++## CAD (KiCad official)++- Symbol: `HT7550-1`+- 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 Youtai Semiconductor Co Ltd datasheet](https://datasheet.lcsc.com/datasheet/pdf/3939d5e60c279f2219306ebd9574e4d6.pdf) (15 pp, sha256 `8a1946363b661b62`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
