Tunable Loop
Recommended values of R
Table 2 shows the recommended values of R
to 1000uF that might be needed for an application to meet output ripple and noise requirements. Selecting R
and C
In applications with tight output voltage limits in the presence of dynamic current loading, additional output
capacitance will be required. Table 3 lists recommended values of R
voltage deviation limits for some common output voltages in the presence of a 15A to 30A step change (50% of
full load), with an input voltage of 12V.
