L6234 Vref capacitor

The AN1088 app note states:

Vref ( Voltage Reference).

This is the internal 10V voltage reference pin to bias the logic and the low voltage circuitry of the device. A 1mF electrolytic capacitor connected from this pin to GND ensures the stability of the DMOS drive circuit. This pin can be externally loaded up to 5mA. Figure 3 and 4 show the typical behavior of the Vref pin.”

I was wondering whether a higher value ceramic capacitor can be used in place of the 1uF electrolytic capacitor on the Vref pin. For example, can we use a 4.7uF, 25V, ceramic, such as  C1608JB1E475K080AC
? The app note does not describe whether there are other capacitor options.

Thanks!
