10 Power Supply Recommendations

The REF50xx family of voltage references features extremely low dropout voltage. With the exception of the REF5020, which has a minimum supply requirement of 2.7V, these references can be operated with a supply of 200mV more than the output voltage in an unloaded condition. For loaded conditions, a typical dropout voltage versus load plot is provided in Figure 6-6. TI recommends a supply bypass capacitor ranging from 1μF to 50μF for REF50xxI and REF50xxAI. TI recommends a supply bypass capacitor ranging from 1μF to 100μF for REF50xxEI.
