XC6220B331MR from TDSEMIC, 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 | Power supply input; maximum input voltage rating is 8 V (absolute maximum) and 7.0 V maximum input voltage per the selection table. |
| 2 | VSS | power_in | Ground terminal. |
| 3 | CE | input | Chip enable input that turns the output on or off; shutdown quiescent current is typically 0.1 uA. |
| 4 | NC | unconnected | No connection (not connected internally). |
| 5 | VOUT | power_out | Regulated output; the XC6220B331 is a 3.3 V output with ±2.5% tolerance, up to 300 mA at Vin=4.3 V. |
