Is the softstart capacitor from the LM2655 shutdown/softstart pin to ground required?

The Shutdown/Softstart pin has two functions, i.e., shutdown command and softstart. The softstart capacitor is highly recommended for proper operation of the regulator (it limits the peak current drawn during startup). Omitting the softstart capacitor may result in a regulator that will not start up.
