AP2204K-1.8TRG1 from MSKSEMI, in a SOT-23-5. 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 | VIN | power_in | Input of supply voltage, with an operating input range of 2V to 24V. |
| 2 | GND | power_in | Ground pin of the regulator, to which the input and output capacitor grounds must return through short, wide copper traces. |
| 3 | CE | input | Enable control input for the regulator. |
| 4 | NC | unconnected | No internal connection. |
| 5 | VOUT | power_out | Output of the regulator, current-limited to 700mA (typical) and stable with an output capacitor of 1µF to 22µF with at least 1mΩ ESR. |
