8.3.3 Minimum Output Capacitance

The TPSM5601R5 requires a minimum amount of ceramic output capacitance for stability depending on the output voltage setting. Figure 8-2 shows the amount of required output capacitance, which is 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 contribute to differences between the standard rated value and the actual effective value of the capacitance. Additional output capacitance above the minimum can be added to reduce output voltage ripple and to improve transient response. When adding additional capacitance above the minimum, the capacitance can be ceramic type, low-ESR polymer type, or a combination of the two.
