external filter must include a 100 nF, max 50 mW ESR capacitor in parallel, to reduce both the high frequency noise and ripple to a minimum.
Depending upon the PCB layout, it might be necessary is to use two 6.8 mF/10 V/ceramic/X7R//SMD1206 in parallel, yielding an improved
CRD_VCC ripple over the temperature range.
