9.2.2.2.5 Output Capacitor Selection

For this IBB design example, use two 22-µF, 25-V, X7R-dielectric ceramic capacitors in 1210 case size connected symmetrically close to the module from the VOUT1 and VOUT2 pins to PGND. The total effective capacitance is approximately 16 µF with DC bias of 12 V.
