Description
The RC1587, RC1587-1.5, and RC1587-3.3 are low dropout
three-terminal regulators with 3A output current capability.
These devices have been optimized for low voltage applica-
tions including VTT bus termination, where transient response
and minimum input voltage are critical. The RC1587 is ideal
for low voltage microprocessor applications requiring a reg-
ulated output from 1.5V to 3.6V with an input supply of 5V
or less. The RC1587-1.5 offers xed 1.5V with 3A current
capability for GTL+ bus VTT termination. The RC1587-3.3
offers xed 3.3V current capability for logic IC operation.
Current limit is trimmed to ensure specied output current and
controlled short-circuit current. On-chip thermal limiting pro-
vides protection against any combination of overload and
ambient temperature that would create excessive junction
temperatures.
The RC1587, RC1587-1.5, and RC1587-3.3 are available in
the industry-standard TO-220, TO-263, TO-263 center cut,
and TO-252 (DPAK) power packages.
