FAN1084

4.5A Adjustable/Fixed Low Dropout Linear Regulator

Features

•

Fast transient response

Low dropout voltage at up to 4.5A

Load regulation: 0.5% typical

On-chip thermal limiting

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

packages

Description

The FAN1084, FAN1084-1.5, and FAN1084-3.3 are low

dropout three-terminal regulators with 4.5A output current

capability. These devices have been optimized for low voltage

applications including V

bus termination, where transient

response and minimum input voltage are critical. The

FAN1084 is ideal for low voltage microprocessor applica-

tions requiring a regulated output from 1.5V to 3.6A with an

input supply of 5V or less. The FAN1084-1.5 offers ﬁxed

1.5V with 4.5A current capabilities for GTL+ bus V

termination. The FAN1084-3.3 offers a ﬁxed 3.3V output

at 4.5A.

On-chip thermal limiting provides protection against any

combination of overload and ambient temperature that

would create excessive junction temperatures.

The FAN1084 series regulators are available in the industry-

standard TO-220, TO-263 center cut, and TO-252 (DPAK)

power packages.
