For normal operation, the REF30xx does not require a capacitor on the output. If a capacitive load is connected, take special care when using low equivalent series resistance (ESR) capacitors and high capacitance. This precaution is especially true for low-output voltage devices; therefore, for the REF3012 use a low-ESR capacitance of 10 μF or less. Figure 29 shows the typical connections required for operation of the REF30xx. A supply bypass capacitor of 0.47 μF is always recommended.
