LMZ10504EXT Application Circuit Schematic and BOMs
This section provides several application solutions with an
associated bill of materials. The compensation for each solu-
tion was optimized to work over the full input range. Many
applications have a fixed input voltage rail. It is possible to
modify the compensation to obtain a faster transient response
for a given input voltage operating point.

In the case where the output voltage is 0.8V, it is recommended to remove R
fbb and keep Rfbt, Rcomp, and Ccomp for a type III compensation.
