Description
The RC1585 and RC1585-1.5 are low dropout three-terminal
regulators with 5A output current capability. These devices
have been optimized for low voltage applications including
V
TT
bus termination, where transient response and mini-
mum input voltage are critical. The RC1585 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 RC1585-1.5 offers 鏗亁ed 1.5V with 5A current capabili-
ties for GTL+ bus V
TT
termination.
Current limit is trimmed to ensure speci鏗乪d output current
and controlled short-circuit current. On-chip thermal limit-
ing provides protection against any combination of overload
and ambient temperature that would create excessive junc-
tion temperatures.
The RC1585 series regulators are available in the industry-
standard TO-220, TO-263, TO-263 center cut and TO-252
power packages.
