In figure 14 they show a graph of typical ESR ratings for capacitors. Feb datawheet, 6. For a 15V input, and 5V 1A output, a 68uH inductor with windings large enough to carry 1A, not the little inductors that look like a resistorand a uFuF cap depending on the Manufacturer are suggested. Tha datasheet specifies the output capacitor capacitance range up to uF but it doesn’t specify the lowest ESR value for that capacitor.
If you didn’t buy the manufacturer’s capacitor that is recommended then you must research the spec’s of what you have and compare it to the spec’s of the ones that are recommended.
