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 | EN | input | Enable control input. Pull high (>1.5V) to turn on the regulator; pull low (<0.4V) to shut down (Ishdn ~0.1µA). Do not float; add a 1MΩ pull-down to GND if the driving source can go high-Z. |+| 2 | GND | power_in | Ground return pin. Maximize copper area for best thermal and noise performance; keep CIN loop area to IN/GND minimal. |+| 3 | LX | power_out | Switching node output; connect to the external inductor (typ. 2.2µH). Internal PFET (110mΩ) sources to VIN and NFET (80mΩ) sinks to GND; peak current limit 3.5A. Minimize PCB copper area on this node to reduce switching noise. |+| 4 | IN | power_in | Supply input, 2.7V to 5.5V (abs max 6.0V). Decouple to GND with at least a 10µF (typ. 22µF) X5R/X7R ceramic capacitor placed close to the IN and GND pins. |+| 5 | FB | input | Output voltage feedback input. Connect to the mid-point of the R1/R2 output divider to program Vout = 0.6V × (1 + R1/R2). Reference is 0.6V (±2%); IFB ±50nA. Keep FB trace away from the LX net. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Silergy Corp |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `SY8089AAAC`+- `SY8089AAACSY8089AAC`++## CAD (KiCad official)++- Symbol: `SY8089AAAC`+- 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/sy8089aaac-datasheet.pdf) (10 pp, sha256 `be137413d9493bb7`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
