GR6203 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 | VDD | power_in | Power supply input; absolute maximum input voltage is 2.0 V, and the stated operating voltage range is 1.0 V to 1.5 V. |
| 2 | LX | output | Power transistor output that drives the inductor; the datasheet gives no separate pin limit for this pin beyond the chip-level ratings. |
| 3 | GND | power_in | Chip ground pin. |
