Description

The RC1585 and RC1585-1.5 are low dropout three-terminal

regulators with 5A output current capability. These devices have been

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

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.
