RC1585 5A Adjustable/Fixed Low Dropout Linear Regulator • Fast transient response • Low dropout voltage at up to 5A • Load regulation typical • Trimmed current limit • On-chip thermal limiting • Standard TO-220 and TO-263 packages • Pro and Pentium II GTL+ bus supply • Low voltage logic supply • Battery-powered circuitry • Post regulator for switching supply 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 VTT 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 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 RC1585 series regulators are available in the industry-standard TO-220 and TO-263 power packages.
