XC6228D122VR-G

MSKSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

XC6228D122VR-G from MSKSEMI, 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 pin; recommended input voltage range is 1.2V to 5.5V, and the absolute maximum VIN to GND is -0.3V to 7V.
2 GND power_in Ground pin for the regulator; input and output capacitor ground connections must return to this pin using short, wide traces.
3 EN input Enable control pin, with EN rising threshold VIH of 1.0V and falling threshold VIL of 0.4V; pulling EN low puts the device into shutdown mode, and VOUT, EN to GND is rated -0.3V to 6V.
4 NC unconnected No-connect pin described in the datasheet as a floating pin, so it should be left unconnected.
5 VOUT power_out Regulated voltage output pin, which supplies up to 300mA of output current; VOUT to VIN is rated -6V to 0.3V.
