LINEAR INTEGRATED CIRCUIT
3A ADJUSTABLE/FIXED LOW
DROPOUT LINEAR
REGULATOR

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.
