Locate the capacitor close to the device. An additional 220µF of bulk capacitance is recommended. See Table 5 for more details. (6) The amount of required output capacitance varies depending on the output voltage (see Table 3 ). The amount of required capacitance must include at least 47µF of ceramic capacitance. Locate the capacitance close to the device. Adding additional capacitance close to the load improves the response of the regulator to load transients. See Table 3 and Table 5 for more details. (7) When using both ceramic and non-ceramic output capacitance, the combined maximum must not exceed 2200µF.
