Description
The FAN1581, FAN1581-1.5, and FAN1581-2.5 are ultra-low
dropout regulators with 5A 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 FAN1581 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 FAN1581-1.5 offers xed 1.5V with
5A current capabilities for GTL+ bus VTT termination. The
FAN1581-2.5 offers xed 2.5V with 5A 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 FAN1581 series regulators are available in the 5-Pin
SPAK and TO-263 power packages.
