7.3.4 Output Capacitors

Table 7-1 lists the TPSM53604 minimum output capacitance. The effects of DC bias and temperature variation must be considered when using ceramic capacitance. For ceramic capacitors, the package size, voltage rating, and dielectric material contributes to differences between the standard rated value and the actual effective value of the capacitance.

When adding additional capacitance above COUT(min), the capacitance can be ceramic type, low-ESR polymer type, or a combination of the two. See Table 7-3 for a preferred list of output capacitors by vendor.
