USB97C223 and USB97C243 Capacitor Selection for Internal Regulator Output Pins
SMSC recommends the use of
ceramic 10uF capacitors
to meet the low ESR requirements of the regulator
output pins of the USB97C223. Ceramic capacitors typically have an ESR of < 0.1 Ohm.
Recommended Capacitors, or equivalent:
Kemet C0805C106K9PACTU
Kemet C1206C106K9PACTU
Panasonic ECJ-2FF0J106Z
Panasonic ECJ-2FF1A106Z
(0805 Package)
(1206 Package)

Tantalum capacitors that have low ESR specifications can also be used, but typically have an ESR closer to 0.5
Ohm.
