TPS6102x - can I use ceramic output caps

Q:

Can I use ceramic output capacitors with the TPS6102x?

 

A:

Ceramic output caps can only be used if a discrete resistor is added in series with them to give an equivalent ESR of at least 30 mOhm.  Per the datasheet, the IC is internally compensated for an output capacitor with at least 30 mOhm of ESR. 

See the attached presentation for what happens when ceramic output capacitors are used.
