DESCRIPTION  
The UZ1085-xx series are low dropout three-terminal regulators  
with 3A 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.

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  
temperature that would create excessive junction temperatures.

FEATURES  
*Pb-free plating product number: UZ1085L-xx  
*Fast transient response  
*Low dropout voltage at up to 3A  
*Load regulation:0.05% typical  
*Trimmed current limit  
*On-chip thermal limiting
