7.3.3 SENSE Pin

In applications where the regulator output is not very close to the load, LP3964 can provide better remote load

regulation using the SENSE pin. Figure 21 depicts the advantage of the SENSE option. LP3961 regulates the

voltage at the OUT pin. Hence, the voltage at the remote load will be the regulator output voltage minus the drop

across the trace resistance. For example, in the case of a 3.3-V output, if the trace resistance is 100 m

Ω, the

the SENSE pin. Connecting the SENSE pin to the remote load will provide regulation at the remote load, as

shown in Figure 21. If the sense option pin is not required, the SENSE pin must be connected to the OUT pin.
