5. This parameter is guaranteed by design and is not 100% production tested.

6. Dropout is defined as either minimum control voltage (VCONTROL) or minimum power voltage (VPOWER) to output voltage differential re-

quired to maintain 1.5% regulation at a particular load.

7. 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

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 1.5% bandgap

reference voltage and carries a bias current of about 50 μA. 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.

This pin is connected to the emitter of the power pass transistor and provides a

regulated voltage capable of sourcing 10 A of current.

This is the supply voltage for the regulator control circuitry. For the device to

regulate, this voltage should be between 1.0 V and 1.4 V (depending on the

output current) greater than the output voltage. The control pin current will be

about 1.0% of the power pin 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 1.0 V and 0.8 V greater than the output voltage depending on the out-

put current. The output load current of 10 A is supplied through this pin.
