Input and output capacitance improv

Input and output capacitance improves the performance of the device; the actual capacitance should be optimized for the particular application. For all applications, a 0.1uF or greater ceramic bypass capacitor between IN and GND is recommended as close to the device as possible for local noise decoupling. This precaution reduces ringing on the input due to power-supply transients. Additional input capacitance may be needed on the input to reduce voltage overshoot from exceeding the absolute-maximum voltage of the device during heavy transient conditions or output shorting. This is especially important during bench testing when long inductive cables are used to connect the evaluation board to the bench power supply. Normally suggested the distance between IC and DC supply is less than 15cm.Output capacitance also needs to be close to IC as possible. When large transient currents are expected on the output, placing a high-value electrolytic capacitor on the output pin is recommended.
