sense-pin connection
SENSE must be connected to OUT for proper operation of the regulator. Normally this connection should be
as short as possible; however, remote sense may be implemented in critical applications when proper care of
the circuit path is exercised. SENSE internally connects to a high-impedance wide-bandwidth amplifier through
a resistor-divider network, and any noise pickup on the PCB trace will feed through to the regulator output.
SENSE must be routed to minimize noise pickup. Filtering SENSE using an RC network is not recommended
because of the possibility of inducing regulator instability.
