Adjustable Output Down to 1.2V
Output Current of 5.0A
The Bay Linear B1084 is Monolithic low power 5.0A
Adjustable and fixed NPN voltage regulator that are easy to
use with minimum external components. All internal circuitry
is designed to operate down to 1V input to output differential
and the dropout voltage is fully specified as a function of load
current. Dropout is guaranteed at a maximum of 1.5V at a
maximum output current. Current limit is trimmed, minimizing
the stress on both the regulator and power source circuitry
under overload conditions. It is suitable for applications
requiring a well-regulated positive output voltage with low
input-output differential voltage.

Similar to industry Standard LT1084
The B1084 Outstanding features include full power usage up
to 5.0Amp of load current internal current limiting and thermal
shutdown. A 10 µF output capacitor is required on these new
devices; how ever, this is usually included in most regulator
design.
