8.1.1.1.2 Output Capacitor

The capacitor value and ESR determines the amount of output voltage ripple and load transient response. Ceramic output capacitors with X5R dielectric or better are recommended .

Equation 8.

Equation 9.

Equation 10.

Where:

Equation 11.

where

• ΔV_OS = The allowable amount of overshoot voltage in load transition
• ΔV_US = The allowable amount of undershoot voltage in load transition
• T_OFF(MIN) = Minimum off time

Select the capacitance value greater than the largest value calculated from Equation 8, Equation 9 and Equation 10. The minimum recommended output capacitance is 44 μF.
