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 the low side of the internally trimmed 1.0% bandgap reference voltage and carries a bias
current of about 50 mA. A resistor divider from Adjust to V
Also, transient response can be improved by adding a small bypass capacitor from this pin to 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 be-
tween 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.
