TDSEMIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
XC6220B251MR 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 input; absolute maximum input voltage is 8 V (7.0 V maximum input voltage in the selection table). |
| 2 | VSS | power_in | Ground terminal. |
| 3 | CE | input | Chip enable input that turns the output on or off, and shutdown quiescent current is typically 0.1 uA. |
| 4 | NC | unconnected | No connection (empty pin). |
| 5 | VOUT | power_out | Regulated output (2.5 V for the 251 option, ±2.5% tolerance); output current is rated to 500 mA absolute maximum and the voltage range is Vss-0.3 V to Vin+0.3 V. |
