DESCRIPTION  
The UTC UZ1084-ADJ/Fixed voltage are low dropout  
1
1
three-terminal 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.  
TO-263-3  
On-chip thermal limiting provides protection against any  
combination of overload and ambient temperature that would  
create excessive junction temperatures.
