standard electrolytic or tantalum capacitors (tested ESR up to 10 Ω) should be OK at the VCC1V8
output. If the ripple voltage at the input is higher than 20 mV, then use 4.7 μF LOW ESR capacitors
(ESR from 0.2 Ω to 2 Ω) at the VCC1V8 output. This is to improve the high-speed signal quality at
the USB side.
