# ME2108A30M3G

**MICRONE** · DC-DC Converters · SOT-23

ME2108A30M3G from MICRONE, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Vss | power_in | Ground pin for the ME2108Axx; the datasheet asks for a solid ground connection because switching current otherwise shifts the internal zero level and can make the IC operate unstably. |
| 2 | Lx | output | Switch pin that drives the inductor, with absolute maximum ratings of 6.5 V on Lx pin voltage and 600 mA on Lx pin current. |
| 3 | Vout | power_in | Output voltage monitor pin that also supplies the IC internal power; the datasheet gives no separate limit for this pin, but the Vdd input voltage absolute maximum is 6.5 V. |
