Features  
Description  
• Low dropout voltage  
• Load regulation: 0.05% typical  
• Trimmed current limit  
The FAN1117A and FAN1117A-1.8, -2.5, -2.85, -3.3 and -5  
are low dropout three-terminal regulators with 1A output  
current capability. These devices have been optimized for low  
voltage where transient response and minimum input voltage  
are critical. The 2.85V version is designed specifically to be  
used in Active Terminators for SCSI bus.  
• On-chip thermal limiting  
• Standard SOT-223, TO-220, and TO-252 packages  
• Three-terminal adjustable or fixed 1.8V, 2.5V, 2.85V,  
3.3V, 5V  
Current limit is trimmed to ensure specified output current  
and controlled short-circuit current. On-chip thermal limiting  
provides protection against any combination of overload and  
ambient temperatures that would create excessive junction  
temperatures.  
Applications  
• Active SCSI terminators  
• High efficiency linear regulators  
• Post regulators for switching supplies  
• Battery chargers  
• 12V to 5V linear regulators  
• Motherboard clock supplies  
Unlike PNP type regulators where up to 10% of the output  
current is wasted as quiescent current, the quiescent current  
of the FAN1117A flows into the load, increasing efficiency.  
The FAN1117A series regulators are available in the  
industry-standard SOT-223, TO-220, and TO-252 (DPAK)  
power packages.
