TPS826711: Output capacitance and module stability

Part Number:TPS826711

An extension of the previous forum post by Nate Enos about the Voltage ripple on the TPS826711.

We'd like to reduce ripple voltage to below 20mVpp from the TPS826711 ideally at Iload > 10mA. This is to support new analog functionality that could be utilized at a variety of system load currents. We already have had to add additional bulk capacitance to the system totalling 6.9uF for ICs on the supply. We're aware this exceeds the reccomended output capacitance, but would like to know the following:

• What observed instabilities should we expect if the bulk capacitance is too high?
• Other solution ideas for reducing ripple to target.
• Any potentially P2P compatible modules that would help us meet the target

Thanks-
