LINEAR INTEGRATED CIRCUIT  
5A ADJUSTABLE/FIXED LOW  
DROPOUT LINEAR  
REGULATOR

TO-220  
„
DESCRIPTION  
The UTC UZ1084-ADJ/Fixed voltages are low dropout  
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-220F  
On-chip thermal limiting provides protection against any  
combination of overload and ambient temperature that would create  
excessive junction temperatures.
