# ME2100A45M3G

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

ME2100A45M3G 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, which must be well grounded because otherwise the internal zero potential shifts with switching current and makes operation unstable. |
| 2 | Lx | output | Switch pin that drives the external inductor, with a rated Lx pin voltage of 6.5 V and Lx output current of 600 mA. |
| 3 | Vout | power_out | Boost output pin, where a 0.1 µF ceramic capacitor is recommended between Vout and Vss and the output capacitor should be at least 10 µF with a voltage rating of at least 3 times the output voltage. |
