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 (VENH ≥ 1.5V) to turn on the regulator; pull low (VENL ≤ 0.4V) to shut down (ISHDN ≈ 0.1µA). Do not float. Absolute max: VIN + 0.6V. |+| 2 | GND | power_in | Ground pin. Return for both power stage and control circuitry. Maximize PCB copper area to this pin for best thermal and noise performance. |+| 3 | LX | power_out | Switching node output. Connect to one end of the external inductor (typical 2.2µH). Internal high-side PFET (260mΩ) and low-side NFET (170mΩ) switch this node between VIN and GND at 1.5MHz. |+| 4 | IN | power_in | Supply input pin, 2.5V to 5.5V operating range (absolute max 6.0V). Decouple to GND with at least a 4.7µF X7R ceramic capacitor placed close to the pin. |+| 5 | FB | input | Output feedback pin. Connect to the mid-point of an external resistor divider from VOUT to GND to program the output voltage: VOUT = 0.6V × (1 + R1/R2), where VREF = 0.6V (±2%). Optional 10-47pF cap across R1 speeds up transient response. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Silergy Corp |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `SY8088AACAAC`++## CAD (KiCad official)++- Symbol: `SY8088AAC`+- 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/sy8088aac-datasheet.pdf) (9 pp, sha256 `d9ec5bc0d2d97bea`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
