GR2188A28M3G from GR, 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 (芯片接地端); the datasheet gives no further electrical limit for this pin. |
| 2 | Lx | output | Inductor connection pin (电感接入端); the absolute maximum LX current is 1000 mA and the maximum voltage on LX is 6 V. |
| 3 | VOUT | power_out | Voltage output pin (电压输出端); the absolute maximum voltage on VOUT and LX is 6 V, and the output is specified at 1.8 V to 3.6 V in 0.1 V steps. |
