5. Dropout is defined as either the minimum control voltage (V
) or minimum power voltage (V
POWER
) 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.

PIN SYMBOL
FUNCTION
1
V
SENSE
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
μ
A. A resistor divider
from Adjust to V
OUT
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
V
OUT
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
V
CONTROL
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
V
POWER
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 out-
put current. The output load current of 3.0 A is supplied through this pin.
