XC6227C121MR-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 | Input supply pin with an operating input voltage range of 1.7V to 6.0V and an absolute maximum rating of VSS-0.3V to 6.5V. |
| 2 | VSS | power_in | Ground pin, the 0V reference for the regulator. |
| 3 | CE | input | Active-high ON/OFF control: high (1.2V to 6.0V) enables the output and low (VSS-0.3V to 0.3V) places the IC in stand-by; this C-type part has an internal pull-down so an open CE pin stops operation. |
| 4 | NC | unconnected | No connection; leave open. |
| 5 | VOUT | power_out | Regulated output (1.2V nominal for this XC6227C121 part, 700mA maximum); reverse current protection blocks current from VOUT to VIN when VOUT is higher than VIN, and an external supply on VOUT must be 6.0V or less. |
