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 / common return for input and output. Pin 1 of the SOT-23 package (bottom-left when viewed from the top with the marking upright). |+| 2 | VOUT | power_out | Regulated fixed +5.0V output (typ. 5.0V, min 4.85V, max 5.15V at IOUT=10mA). Sources up to 100mA (rated) / 150mA (typ.). A small output capacitor (≥1µF) is recommended for stability. |+| 3 | VIN | power_in | Unregulated supply input. Operating input up to 24V (line-regulation spec limit), absolute maximum +30V. Typical dropout ~100mV at 1mA. An input decoupling capacitor is recommended. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TWGMC |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `HT7550`+- `HT7550-1`++## CAD (KiCad official)++- Symbol: `HT7550`+- 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:** [TWGMC datasheet](docs/ht7550-datasheet.pdf) (12 pp, sha256 `d0d358ba595fe029`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
