7.3.8 Output Capacitors
The LMZM33603 minimum and maximum output capacitance listed in Table 1 and Table 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 C_OUT(min), the capacitance may be ceramic type, low-ESR polymer
type, or a combination of the two. See Table 6 for a preferred list of output capacitors by vendor.
