9.2.2.3.1 Input Capacitor

It is recommended to use a combination of capacitors on the input. A small size ceramic capacitor as close as possible from the VIN pin to GND to block high frequency noise and a larger one in parallel for the required capacitance on for good transient behavior of the regulator. X5R or X7R ceramic capacitor are recommended. The input capacitor needs to be large enough to avoid supply voltage dips shorter than 5us as the undervoltage lockout circuitry needs time to react.
