XC6223H281MR-G from Torex Semicon, in a SOT-25. 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 | Power input pin; the series input voltage range is 1.6V to 5.5V. |
| 2 | VSS | power_in | Ground pin for the regulator. |
| 3 | CE | input | ON/OFF control: a level of 1.0V to 5.5V turns the regulator on and 0V to 0.3V puts it in stand-by; for the H-type (XC6223H281MR-G) an open pin is OFF because an internal pull-down holds CE low. |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | power_out | Regulator output; the datasheet recommends a low ESR ceramic output capacitor CL of 1.0µF. |
