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 | VIN | power_in | Power supply input, 1.2V to 5.5V (absolute max 7V). A 1μF ceramic bypass capacitor to GND is recommended close to the pin. |+| 2 | GND | power_in | Device ground reference. |+| 3 | EN | input | Enable control input. VIH ≥ 1.0V enables the regulator; VIL ≤ 0.4V puts the part into shutdown (~100nA typ.). EN input current ≈10nA at VEN=5V. Do not leave floating; tie to VIN for always-on. |+| 4 | NC | unconnected | No internal connection (floating). May be left open or tied to any potential without affecting operation. |+| 5 | VOUT | power_out | Regulated 3.3V output, up to 300mA. Requires a ≥1μF ceramic (or tantalum) output capacitor to GND for stability. Dropout ≈0.18V at ILOAD=300mA for the 3.3V option; internally current-limited (~600mA typ.). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | DSTECH |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `DS8561-33S5S5`+- `DS8561-33S5SS3`+- `DS8561-33S5S3`+- `DS8561-33S5C5`+- `DS8561-33S5D4`+- `DS8561-33S5D6`++## CAD (KiCad official)++- Symbol: `DS8561-33S5`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [DSTECH datasheet](docs/ds8561-33s5-datasheet.pdf) (19 pp, sha256 `b28c6b5e18533c57`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
