7.3.7 Output Capacitors

The LMZM33602 minimum and maximum output capacitance listed in Table 7-1 and Table 7-2 represents the amount of effective 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 will contribute 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 7-5 for a preferred list of output capacitors by vendor.
