Description
The FAN1581, FAN1581-1.2, FAN1581-1.5, and FAN1581-
2.5 are ultra-low dropout regulators with 5A output current
capability. These devices have been optimized for low volt-
age applications including V
TT
sient response and minimum input voltage are critical. The
FAN1581 is ideal for low voltage microprocessor applica-
tions requiring a regulated output from 1.3V to 5.7V with a
power input supply of 1.75V to 6.5V. The FAN1581-1.5
offers fixed 1.5V with 5A current capabilities for GTL+ bus
V
TT
termination. Additionally, the FAN1581-1.2 offers fixed
1.2V output for CPU Bus termination. The FAN1581-2.5
offers fixed 2.5V with 5A current capability for logic IC
operation and processors while minimizing the overall power
dissipation.
bus termination, where tran-
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
TO-263, TO-252 and TO-220 packages.
