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 | CE | input | Chip Enable. Drive high to enable the boost converter output; drive low to shut the device down. Referenced to GND. |+| 2 | VOUT | power_out | Regulated boost output. Factory-trimmed to 2.8 V (SM5701_2.8V option code) with +/-3% accuracy. Absolute max 6.5 V; connect a 22 uF ceramic capacitor (COUT) from VOUT to GND. |+| 3 | NC | unconnected | No internal connection. Leave floating or tie to GND. |+| 4 | GND | power_in | Device ground / return for CIN, COUT, CE and the internal synchronous rectifier. |+| 5 | LX | power_in | Switch node. Connect the boost inductor (recommended 4.7 uH) between the input supply (VIN, 0.9-6.5 V) and LX. Internal power NMOS pulls LX to GND during the on-time; internal synchronous PMOS routes inductor current to VOUT during the off-time. Peak switch current limit typ. 800 mA (600-1000 mA). Absolute max -0.3 V to 6.5 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HICHON SM5701 2 8V |+| Package | SOT-23-3L |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `SM5701_2.8VM`+- `SM5701_2.8VV`+- `SM5701_2.8VS`+- `SM5701_2.8VP`+- `SM5701_2.8VL`++## CAD (KiCad official)++- Symbol: `SM5701_2.8V`+- Footprint: `Package_TO_SOT_SMD:SOT-23-3`+- 3D model: SOT-23-3L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HICHON SM5701 2 8V datasheet](docs/sm5701-2-8v-datasheet.pdf) (11 pp, sha256 `6c830b7b2a7068c0`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
