This device does not require additional input capacitance. If adding additional input capacitance, locate the capacitors close to the device. (4) Internal to the device, 185 µF (nominal) ceramic output capacitance is present. This device does not require additional output capacitance to operate. Adding additional output capacitance near the load improves the response of the device to load transients. (5) The maximum output capacitance listed in the table is the maximum amount that has been tested and validated for proper start-up, stability, and transient response. It may be possible to operate with additional output capacitance, however, additional validation is required.
