Varying the Internal Output Resistance Value

Function

In the voltage regulating mode, internal output resistance has a
value of close to 0



.

The internal output resistance value can be increased for certain
applications, for example simulation of long output cables or
weak automotive batteries. The selected (open-circuit) output
voltage is reduced in proportion to increasing load (figure 7.11 a)
