10 Power Supply Recommendations

To avoid damaging the device, ensure all applied voltages to the pins do not exceed the absolute maximums listed in Absolute Maximum Ratings. Input voltage to the LDOs must be at least 300 mV higher than the largest LDO output voltage to accommodate for the maximum dropout voltage. As power supply requirements varies across applications, consider the expected output voltages and the maximum load currents of each regulator when determining a minimum required current rating for an acceptable power supply.
