RC1587

3A Adjustable/Fixed Low Dropout Linear Regulator

Features

• Fast transient response

• Low dropout voltage at up to 3A

• Load regulation: 0.05% typical

• Trimmed current limit

• On-chip thermal limiting

• Standard TO-220, TO-263, TO-263 center cut,

and TO-252 packages

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 V

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 ﬁxed 1.5V with 3A current

capability for GTL+ bus V

termination. The RC1587-3.3

offers ﬁxed 3.3V current capability for logic IC operation.

Current limit is trimmed to ensure speciﬁed 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.

Applications

• Pentium

Class GTL+ bus supply

• Low voltage logic supply

• Post regulator for switching supply
