This pin is connected to the low side of the internally trimmed 1.5%
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.
2
V
OUT
This pin is connected to the emitter of the power pass transistor and
provides a regulated voltage capable of sourcing 8A of current.

V
IN
This is the supply voltage for the regulator . For the device to regu-
late, this voltage should be between 1.1V and 1.30V (depending on
the output current) greater than the output voltage.

Note 1: The minimum load current is the minimum current required to maintain regulation. Normally the current in the resistor
divider used to set the output voltage is selected to meet the minimum load current requirement.
Note 2: This parameter is guaranteed by design and is not 100% production tested.
Note 3: Dropout voltage is defined as the minimum input/output voltage differential required to maintain 1.5% regulation.
Note 4: This parameter is guaranteed by design, but not parametrically tested in production. However, a 100% thermal shutdown
functional test is performed on each part.
