8.2.2.3 Input Capacitor Selection

A 22-µF input capacitor is recommended to improve line transient behavior of the regulator and EMI behavior of the total power supply circuit. An X5R or X7R ceramic capacitor placed as close as possible to the VIN and PGND pins of the module is recommended. This capacitance can be increased without limit. If the input supply is located more than a few inches from the TPSM83102 or TPSM83103, additional bulk capacitance can be required in addition to the ceramic bypass capacitors. An electrolytic or tantalum capacitor with a value of 47 µF is a typical choice.
