LDO output and input capacitor clarification
So the input capacitor is a local bypass capacitor for stabilizing the voltage and allows current pulses to be drawn. Without input capacitor the regulator can turn into an oscillator. As the datasheet says, input capacitor may not be needed if the input bulk capacitor is close, but it also mentions it might be needed if the output capacitance is large.
