Built-in Switching Regulator of the CY8CLED0xD/G0x

Version 1
    Question: Am I required to use the Built-in Switching Regulator of the CY8CLED0xD/G0x?



    The on-board 5V regulator on CY8CLED0x can be used to power the PowerPSoC device and other devices on the board that need 5V. The total current consumption of these devices including PowerPSoC should be less than 250mA. This is because the maximum current that the regulator can supply is 250mA. If the application designer wants to drive the PowerPSoC device with external 5V supply, he can safely shut down the internal regulator.
