4. This parameter is guaranteed by design and is not 100% production tested.
5. Dropout is defined as either the minimum control voltage (VCONTROL) or minimum power voltage (VPOWER) to output voltage differential
required to maintain 1.0% regulation at a particular load current.
6. This parameter is guaranteed by design, but not parametrically tested in production. However, a 100% thermal shutdown functional test
is performed on each part.

FUNCTION
1
VSENSE
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.
2
Adjust
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 VOUT and from Adjust to ground sets the
output voltage. Also, transient response can be improved by adding a small bypass capacitor from this pin
to ground.
3
VOUT
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.
4
VCONTROL
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.
5
VPOWER
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.
