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 (VEN,H ≥ 1.2V) to turn on the regulator; drive low (VEN,L ≤ 0.4V) to shut down (ISHDN ~0.1µA). Do not leave floating; add a 1MΩ pull-down to GND if driven by a high-Z source. |+| 2 | GND | power_in | Ground reference for the IC. Connect to the system ground plane with a low-impedance path; the CIN loop between IN and GND must be minimized. |+| 3 | LX | output | Switching node output of the internal high-side/low-side FET bridge. Connect to the external inductor (e.g. 1.0µH). Rated -0.3V to 6.0V (transient -3V/+7V <40ns). Minimize PCB copper area on this net to reduce EMI. |+| 4 | IN | power_in | Power supply input, 2.5V to 5.5V (abs max 6.0V). Decouple to GND with at least a 10µF X5R (or better) ≥6.3V ceramic capacitor placed close to the pin. |+| 5 | FB | input | Output voltage feedback input. Connect to the midpoint of the RH/RL divider from VOUT to GND to program VOUT = 0.6V × (1 + RH/RL). Internal reference is 600mV (591-609mV). A feed-forward cap (e.g. 22pF) across RH improves transient response. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Silergy Corp |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `SY8089A1AACAAC`++## CAD (KiCad official)++- Symbol: `SY8089A1AAC`+- 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/sy8089a1aac-datasheet.pdf) (10 pp, sha256 `8587214d50cc945a`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
