Hello

For ADXRS450 gyro, is it possible to possible to provide 5V for boost regulator and 3.3V for others as shown in image? The intention is to reduce the noise on power supply plane due to switching regulator.

Since output of 5V and 3.3V sources are different, there is a time difference when power arrives to chip. Some chips may damage because of this that's why I have this doubt. Is it recommended to use this type of power supply?

Thanks
