Applications Information (Continued)

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

Ω, the voltage at the remote load will be

3V with 3A of load current, I

LOAD. 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.
