UTC UZ1086 LINEAR INTEGRATED CIRCUIT
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.
