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 reference for the regulator. Connect directly to the system ground plane. |+| 2 | VOUT | power_out | Regulated voltage output. For the -25 variant the fixed output is 2.5 V, capable of sourcing up to 300 mA. Requires a 1 μF ceramic (or tantalum) output capacitor to GND for stability. |+| 3 | VIN | power_in | Power supply input. Accepts 1.2 V to 5.5 V; absolute maximum 7 V relative to GND. Bypass with a 1 μF ceramic capacitor to GND close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | DSTECH |+| Package | SOT23-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `DS8561-25S3`+- `DS8561-25S3SS3`+- `DS8561-25S3S5`+- `DS8561-25S3C5`+- `DS8561-25S3D4`+- `DS8561-25S3D6`++## CAD (KiCad official)++- Symbol: `DS8561-25S3`+- Footprint: `Package_TO_SOT_SMD:SOT-23-3`+- 3D model: SOT23-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [DSTECH datasheet](docs/ds8561-25s3-datasheet.pdf) (19 pp, sha256 `b28c6b5e18533c57`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
