APPLICATION INFORMATION
For the TPS60101, 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 become competitive in size soon.

Tantalum
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.

power dissipation
The power dissipated in the TPS60101 depends on output current and is approximated by:
P
DISS + IO
2V
IN
* V
O for IQ tt IO
PDISS must be less than that allowed by the package rating. See the ratings for 20-PowerPAD package
power-dissipation limits and deratings.
