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 | OUT | power_out | Switched power output pin. Connect a 10µF decoupling capacitor to GND. Delivers up to 2A load current from the internal P-channel MOSFET (R_DS(on) ~63mΩ typ.). No body diode, so reverse current from OUT to IN is blocked when disabled. |+| 2 | GND | power_in | Device ground reference. Also the case position for θ_JC thermal measurement per JEDEC 51-3. |+| 3 | ISET | input | Current-limit programming pin. Connect a resistor R_SET from this pin to GND to set the over-current threshold: I_LIM (A) = 6800 / R_SET (Ω). Minimum programmable limit is 0.4A; operation above 2A is not recommended. |+| 4 | EN | input | Active-high ON/OFF enable input. V_EN(H) ≥ 2V to enable, V_EN(L) ≤ 0.8V to disable; leakage 1µA at 5V. Must not be left floating. |+| 5 | IN | power_in | Power input pin, 2.4V to 5.5V operating range (6V absolute maximum). Decouple with a 10µF ceramic capacitor to GND, placed close to the pin, to prevent input droop during hot-plug and to suppress ringing from output short events. UVLO threshold ~2.3V with 0.1V hysteresis. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Silergy Corp |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `SY6280AAACSY6280AAC`+- `SY6280AAAC`++## CAD (KiCad official)++- Symbol: `SY6280AAAC`+- 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:** [Silergy Corp datasheet](docs/sy6280aaac-datasheet.pdf) (10 pp, sha256 `cf79e56d5b13e99c`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
