lower than 10µF is used, then problems with impedance interactions or switching noise can affect the LM3478. To improve performance, especially with V belowIN volts, it is recommended to use a 20Ω resistor at the input to provide a RC filter. The resistor is placed in series with the V pin with only a bypass
