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
VTT 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 VTT 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.
