The value of ESR between ceramic and tantalum capacitors differs by about two orders of magnitude as illustrated below.
The characteristics of tantalum capacitors also vary widely according to manufacturer. The output capacitor becomes
a part of the phase compensation in a LDO regulator using a PNP pass transistor. Because of this, it is necessary to
optimize the phase compensation in the IC for use with ceramic or tantalum capacitors.
