11 Power-Supply Recommendations

The REF20xx family of references feature an extremely low-dropout voltage. These references can be operated with a supply of only 20 mV above the output voltage. For loaded reference conditions, a typical dropout voltage versus load is shown in Figure 11-1. A supply bypass capacitor ranging between 0.1 µF to 10 µF is recommended.
