GR6220B181MR-G from GR, 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 pin for the regulator; the datasheet gives an input voltage range of 1.8 V to 7 V, with an absolute maximum Vin of 8 V. |
| 2 | VSS | power_in | Ground pin of the regulator. |
| 3 | CE | input | Enable pin: a level of 1.6 V to VIN enables the output and 0 to 0.5 V shuts it down, with shutdown current of 0.1 µA typical. |
| 4 | NC | unconnected | Not connected (marked 空, empty, in the datasheet). |
| 5 | VOUT | power_out | Regulated output pin; for this 1.8 V variant the nominal output is 1.8 V with ±2.5% tolerance, and the absolute maximum output current is 500 mA. |
