9.3 Power Supply Recommendations

The REF61xx family of references have extremely low dropout voltage. The dropout specifications can be found in Section 6.5. A minimum 0.1 µF decoupling capacitor must be connected between the VIN and GND_F pins of the REF61xx. A typical dropout voltage versus load is shown in Figure 9-8.
