Remote sensing operation
When load is physically far away from device output, the adjustable line can be set as a
kelvin sense line by implementing the divider resistor bridge as close as possible form
device, with a decoupling capacitor. The adjust pin kelvin sense line (to be not coupled with
power line) picks-up load voltage (load also locally decoupled with a capacitor). This layout
eliminates ohmic drop in load power wire. Similarly, by taking advantage of two separate
ground terminals: power ground pin shall be directly connected to load ground terminal
which is also the system ground, device signal ground shall be separately connected to load
ground terminal by another kelvin line: In this way, ground ohmic errors are minimized
because the only current flowing into device signal ground pin kelvin line is device Iq (a
matter of a few mA).
