Fairchild Semiconductor FAN1581
The FAN1581, FAN1581x12, FAN1581-1.5, and FAN15812.5 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 regulated output from 1.3V to 5.7V with a power input supply of 1.75V to 6.5V.| Part No. | FAN1581 |

DESCRIPTION
The FAN1581-1.5 offers fixed 1.5V with 5A current capabilities for GTL+ bus VTT termination. Additionally, the FAN1581x12 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. Current limit ensures controlled short-circuit current. On-chip thermal limiting provides protection against any combination of overload and ambient temperature that would create excessive junction temperatures. The FAN1581 series regulators are available in the 5-pin SPAK, TO-263, TO-252 and TO-220 packages.APPLICATIONS
