DROPOUT LINEAR

REGULATOR

DESCRIPTION

The UTC UZ1086 and UZ1086-1.8V, 2.5V, 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 up to 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 1.8V, 2.5V, 2.85V, 3.3V, 5V
