APPLICATIONS INFORMATION
negative side of the load. Although it may not be immedi-
ately obvious, best load regulation is obtained when the
top of the resistor divider, R1, is connected
directly to the
case
not to the load. This is illustrated in Figure 3. If R1
were connected to the load, the effective resistance be-
tween the regulator and the load would be:

Connected as shown, RP is not multiplied by the divider
ratio. RP is about 0.004Ω per foot using 16 gauge wire.
This translates to 4mV/ft at 1A load current, so it is
important to keep the positive lead between regulator and
load as short as possible, and use large wire or PC board
traces.
