Features  
Description  
• Ultra Low dropout voltage, 0.4V typical at 5A  
• 1.2V Versions available for GTL termination  
• Remote sense operation  
• Fast transient response  
• Load regulation: 0.05% typical  
• 0.5% typical initial accuracy  
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 VTT bus termination, where tran-  
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  
VTT 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.  
• On-chip thermal limiting  
• TO-263, TO-252 and TO-220 packages  
Applications  
• Support of GTL+ bus supply  
• Low voltage logic supply  
• Embedded Processor supplies  
• Split plane regulator  
• 2.5V, and 1.8V Logic Families  
• DDR Termination Supply  
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.
