**Slkor SLKORMICRO Elec** · DC-DC Converters · SOT-23

SL2188A33XG from Slkor SLKORMICRO Elec, 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 | Chip ground terminal (SOT-23 pin 1). |
| 2 | Lx | output | Inductor connection terminal (switching node); the datasheet limits the LX maximum current to 1000 mA and the maximum voltage applied to the LX and VOUT pins to 6 V. |
| 3 | VOUT | power_out | Voltage output terminal; the output voltage for the 3.3 V version is 3.3 V with a tolerance of ±2.5%, and the maximum voltage applied to VOUT is 6 V. |
