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.
