XC6221A292MR-G

Torex Semicon · Linear Voltage Regulators (LDO) · SOT-25

XC6221A292MR-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; operating input voltage range is 1.6V to 6.0V, with absolute maximum rating VSS - 0.3 to 6.5V.
2 VSS power_in Ground pin for the regulator.
3 CE input ON/OFF control: a high level (1.2V ≤ VCE ≤ 6.0V) enables the IC and a low level (VCE ≤ 0.3V) puts it in stand-by; for the XC6221A/B (no pull-down) an open CE pin gives an undefined state.
4 NC unconnected No connection.
5 VOUT power_out Regulated output pin; output current is limited to 200mA minimum (250mA typical), and the absolute maximum rating is VSS - 0.3 to VIN + 0.3V.
