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 | Vss | power_in | Ground reference pin. Must be tied to a solid ground plane; if Vss is not well grounded the internal zero reference shifts with switching current and operation becomes unstable. |+| 2 | Lx | output | Switch node - drain of the internal NMOS boost switch. Connects to the junction of the external inductor and Schottky rectifier (e.g. 1N5817/1N5819). Absolute max VLX = 6.5V; max switch current ILX = 600mA; switch-on current typical ~100mA (max 160mA at VLX=0.4V, Vout=Vout*0.95). |+| 3 | Vout | power_out | Regulated boost output and internal-circuit supply / output-voltage sense pin. Factory-trimmed to 3.0V (±2.5%) for the ME301C variant. Bypass with ≥10µF tantalum (47µF/16V recommended) plus 0.1µF ceramic close to the pin. Also powers the internal control circuitry. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MICRONE |+| Package | SOT-23-3L |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `ME301CMG`+- `ME301CMGM`+- `ME301CMGPG`+- `ME301CMGP`++## CAD (KiCad official)++- Symbol: `ME301CMG`+- 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:** [MICRONE datasheet](docs/me301cmg-datasheet.pdf) (None pp, sha256 `c6c98bd13fa393f3`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
