Typical Applications
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 minimum 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 fixed 1.5V with 5A current capabilities
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 RC1585 series regulators are available in the industry-standard
TO-220 and TO-263 power packages
