This Kelvin sense pin allows for remote sensing of the output voltage at the load for improved regulation. It is
internally connected to the positive input of the voltage sensing error amplifier.
This pin is connected to system ground.
This pin is connected to the emitter of the power pass transistor and provides a regulated voltage capable of
sourcing 3.0 A of current.
This is the supply voltage for the regulator control circuitry. For the device to regulate, this voltage should be
between 0.9 V and 1.3 V (depending on the output current) greater than the output voltage. The control pin
current will be about 1.0% of the output current.
This is the power input voltage. This pin is physically connected to the collector of the power pass transistor. For
the device to regulate, this voltage should be between 0.1 V and 0.6 V greater than the output voltage depending
on the output current. The output load current of 3.0 A is supplied through this pin.
