# ME2188A30PG

**MICRONE** · DC-DC Converters · SOT-89-3

ME2188A30PG from MICRONE, in a SOT-89-3. 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 for the SOT89-3 package; the datasheet requires GND to be well grounded, otherwise the internal zero potential shifts with switching current and operation becomes unstable. |
| 2 | VOUT | power_out | Regulated boost output pin, with an absolute maximum voltage of -0.3 to 6 V; output accuracy is ±2% and output current is rated at 300 mA. |
| 3 | LX | bidirectional | Energy conversion (switching) pin connecting the external inductor, with an absolute maximum pin voltage of -0.3 to 6 V and a maximum LX pin current of 1000 mA. |
