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 | VSS | power_in | Ground / negative supply return (VSS). All internal reference, error amplifier, and pass-device return currents flow through this pin; tie directly to the system ground plane. |+| 2 | VIN | power_in | Unregulated input supply (VIN). Operating range up to 10 V absolute maximum; must exceed VOUT by at least the dropout (~120 mV typ at IOUT=100 mA, VOUT=5.0V). Bypass with a ceramic capacitor close to the pin. |+| 3 | VOUT | power_out | Regulated 5.0 V output (VOUT) from the internal PMOS pass device. Sources up to 300 mA (subject to package power dissipation, 500 mW for SOT-89); requires an output capacitor for stability and load transient response. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UTC Unisonic Tech |+| Package | SOT-89 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `UR6225G-50-AB3-C-RUR6225G-xx-AB3-C-R`+- `UR6225G-50-AB3-C-RUR6225L-xx-AB3-C-R`+- `UR6225G-50-AB3-C-RUR6225G-xx-AE3-3-R`+- `UR6225G-50-AB3-C-RUR6225L-xx-AE3-3-R`+- `UR6225G-50-AB3-C-RUR6225G-xx-AF5-C-R`+- `UR6225G-50-AB3-C-RUR6225L-xx-AF5-C-R`+- `UR6225G-50-AB3-C-RUR6225G-xx-AF5-F-R`+- `UR6225G-50-AB3-C-RUR6225L-xx-AF5-F-R`+- `UR6225G-50-AB3-C-RUR6225G-xx-T92-C-B`+- `UR6225G-50-AB3-C-RUR6225G-xx-T92-C-K`+- `UR6225G-50-AB3-C-RUR6225G-xx-T92-B-B`+- `UR6225G-50-AB3-C-RUR6225G-xx-T92-B-K`+- `UR6225G-50-AB3-C-RUR6225L-xx-T92-C-B`+- `UR6225G-50-AB3-C-RUR6225L-xx-T92-C-K`+- `UR6225G-50-AB3-C-RUR6225L-xx-T92-B-B`+- `UR6225G-50-AB3-C-RUR6225L-xx-T92-B-K`++## CAD (KiCad official)++- Symbol: `UR6225G-50-AB3-C-R`+- 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:** [UTC Unisonic Tech datasheet](docs/ur6225g-50-ab3-c-r-datasheet.pdf) (15 pp, sha256 `7f6be1ca01fc03e5`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
