3.0A Low Dropout Voltage Regulator
Adjustable
B1085
Description
The Bay Linear B1085 is Monolithic low power 3.0A
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.
The B1085 Outstanding features include full power usage up
to 3.0Amp 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.
The B1085 is offered in a 3-pin TO-220, TO-263 & TO-252
packages compatible with other 3 terminal regulators. For 5A
Low dropout Regulator refer to the BL1084 data sheet.
