XC6227C121MR-G

Torex Semicon · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-25

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.
