RC1585

5A Adjustable/Fixed Low Dropout Linear Regulator

Features

Description

• Fast transient response

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

• Low dropout voltage at up to 5A

• Load regulation: 0.05% typical

• Trimmed current limit

bus termination, where transient response and mini-

• On-chip thermal limiting

• Standard TO-220, TO-263, TO-263 center cut and TO-252

packages

mum 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 capabili-

ties for GTL+ bus V termination.

Applications

• Pentium^®class GTL+ bus supply

• Low voltage logic supply

Current limit is trimmed to ensure speciﬁed output current

and controlled short-circuit current. On-chip thermal limit-

ing provides protection against any combination of overload

and ambient temperature that would create excessive junc-

tion temperatures.

• Post regulator for switching supply

The RC1585 series regulators are available in the industry-

standard TO-220, TO-263, TO-263 center cut and TO-252

power packages.
