I'm looking at this switching regulator: http://www.ti.com/lit/ds/symlink/lm2675.pdf.

For it'sits input and output capacitors it recommends tantalum or electrolytic capacitors. It mentions in section 9.2.1.2.4 that a ceramic capacitor on the input can cause ringing. Admittedly, I haven't had to make a lot of power supplies but the ones I've used have been fine with ceramics.

I ask because I am space limited and a ceramic capacitor at the same value and voltage rating is much smaller. Why does it specify only tantalum and electrolytic capacitors in the datasheet?

Why do some switching regulator require tantalum or electrolytic capacitors instead of ceramic?
