1.5A ADJUSTABLE/FIXED LOW 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.
