FAN1585A

5A Adjustable/Fixed Low Dropout Linear Regulator

Features

Description

• Fast transient response

The FAN1585A, FAN1585A-1.5, and FAN1585A-1.8 are

low dropout three-terminal regulators with 5A output current

capability. These devices have been optimized for low volt-

• Low dropout voltage at up to 5A

• Load regulation: 0.05% typical

• Trimmed current limit

age applications includingV bus termination for FC-PGA,

• On-chip thermal limiting

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

where transient response and minimum input voltage are

critical. The FAN1585A-1.5 offers ﬁxed 1.5V with 5A

current capabilities for AGTL+ bus V termination for

FC-PGA. The FAN1585A is ideal for low voltage micro-

processor applications requiring a regulated output from

1.5V to 3.6V with an input supply of 5V or less, or for

FC-PGA applications with signiﬁcant trace resistance.

Applications

• AGTL+ bus supply for FC-PGA

• Low voltage logic supply

• Post regulator for switching supply

• 3.3V to 1.5V linear regulator

• 5V to 1.8V linear regulator

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.

The FAN1585A series regulators are available in the industry-

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

packages.
