The Rtop and Rbottom table is verified during validation as well as the loop stability, so we recommend to use the value provided. However, it is possible to increase the Rtop and Rbot to reduce the power consumption. From the DC point of view, it should be totally fine to adjust the Rtop and Rbot but keep the ratio same. Just need to be aware of the pole and zero formed by the Rtop, Rbottom and Ctop.
There’s a zero at 1/(2pi*Rtop*Ctop) and a pole at 1/(2pi*Rtop/Rbot*Ctop). Changing the Rtop and Rbot basically change the position of the zero and pole pair, so as long as there are no instability issues after changing them, it should be perfectly fine.
