Connect to the system ground plane and to the negative terminal of the input and output bypass capacitors. |+| 2 | VIN | power_in | Unregulated input supply. Absolute maximum 30V. Bypass with a 10µF capacitor to GND close to the pin (see application circuit). |+| 3 | VOUT | power_out | Regulated 5.0V ±3% output (4.85V-5.15V typ at VIN=7V, IOUT=10mA). Continuous output current 60-100mA. Bypass with a 10µF capacitor to GND for stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW Youtai Semiconductor Co Ltd |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## CAD (KiCad official)++- Symbol: `HT7550S`+- Footprint: `Package_TO_SOT_SMD:SOT-23`+- 3D model: SOT-23 (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/fbf7338911b0248282bee4442d846012.pdf) (15 pp, sha256 `c8d27849b87576cd`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
