# ME2188A30XG

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

ME2188A30XG 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 | GND | power_in | Ground pin; the datasheet requires GND to be well grounded, because otherwise the internal zero potential shifts with switching current and operation becomes unstable. |
| 2 | LX | output | Energy-conversion switch pin connected to the inductor; absolute maximum LX pin voltage is -0.3 to 6 V and LX pin current is 1000 mA. |
| 3 | VOUT | power_out | Boost regulator output pin; absolute maximum VOUT pin voltage is -0.3 to 6 V, and a 0.1 µF ceramic capacitor is recommended between VOUT and GND. |
