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.
FEATURES
*Fast transient response
*Low dropout voltage at up to 3A
*Load regulation:0.05% typical
*Trimmed current limit
*On-chip thermal limiting
