8.3.4 Output Capacitors

Table 8-1 lists the TLVM13640 minimum amount of required output capacitance. The effects of DC bias and temperature variation must be considered when using ceramic capacitance. For ceramic capacitors in particular, the package size, voltage rating, and dielectric material contribute to differences between the standard rated value and the actual effective value of the capacitance.

When including additional capacitance above COUT(min), the capacitance can be ceramic type, low-ESR polymer type, or a combination of the two. See Table 8-3 for a preferred list of output capacitors by vendor.
