Description
The FAN1582, FAN1582-1.5, and FAN1582-2.5 are ultra-low
dropout regulators with 3A output current capability. These
devices have been optimized for low voltage applications
including VTT bus termination, where transient response and
minimum input voltage are critical. The FAN1582 is ideal
for low voltage microprocessor applications requiring a reg-
ulated 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 capabilities for GTL+ bus VTT termination. The
FAN1582-2.5 offers fixed 2.5V with 3A current capability
for logic IC operation and processors while minimizing the
overall power dissipation.
Current limit ensures controlled short-circuit current. On-chip
thermal limiting provides protection against any combination
of overload and ambient temperature that would create exces-
sive junction temperatures.
The FAN1582 series regulators are available in the 5-Pin
SPAK, TO-252 DPAK, and TO-263 power packages.
