The REF33xx is a family of low-power, precision band-gap voltage references that are specifically designed for extremely low dropout, excellent initial voltage accuracy with a high output current. A simplified block diagram of the REF33xx is shown in the Functional Block Diagram section. Figure 17 shows the typical connections for the REF33xx. A supply bypass capacitor ranging between 1 μF to 10 μF is recommended. The total capacitive load at the output must be between 0.1 μF to 10 μF to ensure output stability.
