FAN1581  
5A Adjustable/Fixed Ultra Low Dropout  
Linear Regulator  
Features  
Description  
• Ultra Low dropout voltage, 0.4V typical at 5A  
• Remote sense operation  
• Fast transient response  
• Load regulation: 0.05% typical  
• 0.5% initial accuracy  
• On-chip thermal limiting  
The FAN1581, FAN1581-1.5, and FAN1581-2.5 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 reg-  
ulated 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. The  
FAN1581-2.5 offers fixed 2.5V with 5A current capability  
for logic IC operation and processors while minimizing the  
overall power dissipation.  
• 5-Pin SPAK and TO-263 packages  
Applications  
• Pentium® Processors  
• PowerPC, AMD K5 and K6 processors  
• Pentium support of GTL+ bus supply  
• Low voltage logic 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.  
• Embedded Processor supplies  
• Split plane regulator  
• New 2.5V and 1.8V Logic Families  
The FAN1581 series regulators are available in the 5-Pin  
SPAK and TO-263 power packages.
