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.
