This pin is connected to the low side of the internally trimmed
2% bandgap reference voltage and carries a bias current of
about 70µA. A resistor divider from Adj to V
OUT
and from Adj
to ground sets the output voltage. 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 10A of
current.
This is the supply voltage for the regulator. For the device to
regulate, this voltage should be between 1.2V and 1.40V
(depending on the output current) greater than the output
voltage.
