DESCRIPTION

The UTC UZ1086 and 2.85V, 3.3V and 5V are low dropout three-terminal regulators with 1.5A output current capability. These devices have been optimized for low voltage where transient response and minimum input voltage are critical. The 2.85V version is designed specifically to be used in Active Terminators for SCSI bus. 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 temperatures that would create excessive junction temperatures. Unlike PNP type regulators where 10% of the output current is wasted as quiescent current, the quiescent current of the UZ1086 flows into the load, increasing efficiency.

FEATURES

*Low dropout voltage *Load regulation: 0.05% typical *Trimmed current limit *On-chip thermal limiting *Three-terminal adjustable or fixed 3.3V, 5V

See thermal regulation specifications for changes in output voltage due to heating effects. Load and line regulation are measured at a constant junction temperature by low duty cycle pulse testing. 2. Line and load regulation are guaranteed up to the maximum power dissipation. Power dissipation is determined by input/output differential and the output current. Guaranteed maximum output power will not be available over the full input/output voltage range.
