Typical Application Circuits
This section provides several application solutions with a bill
of materials. All bill of materials reference the below figure.
The compensation for these solutions were optimized to work
over a wide range of input and output voltages; if a faster
transient response is needed reduce the value of C
and
calculate the new value for R
C1
as outline in the design guide.
