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 voltage 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 microprocessor 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.
