UTC UZ1084
LINEAR INTEGRATED CIRCUIT
5A ADJUSTABLE/FIXED LOW
DROPOUT LINEAR REGULATOR
DESCRIPTION
The UTC UZ1084-ADJ/Fixed voltage are low dropout
three-terminal regulators with 5A output current capability.
These devices have been optimized for low voltage
applications including V
TT
bus termination, where transient
response and minimum input voltage are critical.
On-chip thermal limiting provides protection against any
combination of overload and ambient temperature that would
create excessive junction temperatures.
