1 / 13 page www.fairchildsemi.com REV. 1.1.6 7/8/05 Features •Fast transient response •Low dropout voltage at up to 5A • Load regulation: 0.05% typical •Trimmed current limit • On-chip thermal limiting •Packages: TO-220, TO-252, TO-263 and TO-263 Centercut Applications •AGTL+ bus supply for FC-PGA •Low voltage logic supply • Post regulator for switching supply • 3.3V to 1.5V linear regulator • 5V to 1.8V linear regulator 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 VTT bus termination for FC-PGA, where transient response and minimum input voltage are critical. The FAN1585A-1.5 offers fixed 1.5V with 5A current capabilities for AGTL+ bus VTT 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 significant trace resistance. Current limit is trimmed to ensure specified 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-252, TO-263 and TO-263 Centercut power packages.
