APPLICATION INFORMATION
For the TPS60111, the smallest board space size can be achieved using Sprague’s 595D-series tantalum
capacitors for input and output. However, with the trend towards high capacitance ceramic capacitors in smaller
size packages, these type of capacitors might soon become competitive in size.

Table 6 lists the manufacturers of recommended capacitors. In most applications surface-mount tantalum
capacitors will be the right choice. However, ceramic capacitors will provide the lowest output voltage ripple due
to their typically lower ESR.
