Applications Information

Sense Pin
In applications where the regulator output is not very close to
the load, LP3966 can provide better remote load regulation
using the SENSE pin. Figure 2 depicts the advantage of the
SENSE option. LP3963 regulates the voltage at the output
pin. Hence, the voltage at the remote load will be the regula-
tor output voltage minus the drop across the trace resis-
tance. For example, in the case of a 3.3V output, if the trace
resistance is 100m
, the voltage at the remote load will be
3V with 3A of load current, I
. The LP3966 regulates the
voltage at the sense pin. Connecting the sense pin to the re-
mote load will provide regulation at the remote load, as
shown in Figure 2 If the sense option pin is not required, the
sense pin must be connected to the V
OUT
pin.
