Description
The RC1584 and RC1584-1.5 are low dropout three-terminal
regulators with 7A output current capability. These devices
have been optimized for low voltage applications including
V
TT
bus termination, where transient response and minimum
input voltage are critical. The RC1584 is ideal for low
voltage microprocessor applications requiring a regulated
output from 1.5V to 3.6V with an input supply of 5V or less.
The RC1584-1.5 offers fixed 1.5V with 7A current capabil-
ity for GTL+ bus V
TT
termination.
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.
The RC1584 and RC1584-1.5 are available in the industry-
standard TO-220, TO-263 and TO-263 center cut power
packages.
