Description
The FAN1585A, FAN1585A-1.5, and FAN1585A-1.8 are
low dropout three-terminal regulators with 5A output current
capability. These devices have been optimized for low volt-
age applications including V
TT
bus termination for FC-PGA,
where transient response and minimum input voltage are
critical. The FAN1585A-1.5 offers 鏗亁ed 1.5V with 5A
current capabilities for AGTL+ bus V
TT
termination for
FC-PGA. The FAN1585A is ideal for low voltage micro-
processor applications requiring a regulated output from
1.5V to 3.6V with an input supply of 5V or less, or for
FC-PGA applications with signi鏗乧ant trace resistance.
Current limit is trimmed to ensure speci鏗乪d output current
and controlled short-circuit current. On-chip thermal limit-
ing provides protection against any combination of overload
and ambient temperature that would create excessive junc-
tion temperatures.
The FAN1585A series regulators are available in the industry-
standard TO-220, TO-263 and TO-263 center cut power
packages.
