Description
The FAN1582, FAN1582-1.5, and FAN1582-2.5 are ultra
low dropout regulators with 3A output current capability.
These devices are optimized for low-voltage applica-
tions, including V
response and minimum input voltage are critical. The
FAN1582 is ideal for low-voltage microprocessor appli-
cations requiring a regulated output from 1.3V to 5.7V
with a power input supply of 1.75V to 6.5V.
The FAN1582-1.5 offers fixed 1.5V with 3A current capa-
bilities for GTL+ bus V
The FAN1582-2.5 offers fixed 2.5V with 3A current capa-
bility for logic IC operation and processors while minimiz-
ing the overall power dissipation.
Current limit ensures controlled short-circuit current. On-
chip thermal limiting provides protection against combi-
nation of overload and ambient temperature that would
create excessive junction temperatures.
The FAN1582 is available in a 5-pin TO-263 power package.
