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 the regulator on; drive low (VEN,L ≤ 0.4V) to shut down (shutdown current 0.1µA typ). Do not leave floating; add a 1MΩ pull-down to GND when the driving source can be high-Z. |+| 2 | GND | power_in | Ground return pin for the IC and the internal low-side synchronous FET. Maximize copper connection to GND plane for best thermal and noise performance. |+| 3 | LX | output | Switching-node output of the internal power stage. Connect to the external inductor (typ. 1.0µH). PCB copper area on this net must be minimized to avoid noise coupling. Absolute LX range -0.3V to 6.0V (tested to -3V/+7V for <40ns transients). |+| 4 | IN | power_in | Power supply input, 2.5V to 5.5V operating range (absolute max 6.0V). Decouple to GND with at least a 10µF X5R ceramic capacitor placed close to the IN/GND pins to minimize loop area. |+| 5 | FB | input | Output voltage feedback pin. Connect to the mid-point of the output resistor divider (RH from VOUT to FB, RL from FB to GND) to program VOUT = 0.6 × (1 + RH/RL). Internal reference VREF = 0.6V (588-612mV). Keep this trace away from LX to avoid noise pickup. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Silergy Corp |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `SM8082AAACAAAC`++## CAD (KiCad official)++- Symbol: `SM8082AAAC`+- 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/sm8082aaac-datasheet.pdf) (10 pp, sha256 `3d1af3cb0c77bf0a`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
