UTC UZ1085 LINEAR INTEGRATED CIRCUIT

3A ADJUSTABLE/FIXED LOW

DROPOUT LINEAR REGULATOR

DESCRIPTION

The UZ1085-ADJ,UZ1085-Fixed 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.
