FAN1582

3A Adjustable/Fixed Ultra Low Dropout

Linear Regulator

Description

Features

The FAN1582, FAN1582-1.5, and FAN1582-2.5 are ultra-low

dropout regulators with 3A output current capability. These

devices have been optimized for low voltage applications

• Ultra Low dropout voltage, 0.4V typical at 3A

• Remote sense operation

• Fast transient response

• Load regulation: 0.05% typical

• 0.5% initial accuracy

• On-chip thermal limiting

including V bus termination, where transient response and

minimum input voltage are critical. The FAN1582 is ideal

for low voltage microprocessor applications requiring a reg-

ulated output from 1.3V to 5.7V with a power input supply

of 1.75V to 6.5V. The FAN1582-1.5 offers ﬁxed 1.5V with

• 5 Pin standard TO-220 and TO-263 packages

3A current capabilities for GTL+ bus V termination. The

Applications

FAN1582-2.5 offers ﬁxed 2.5V with 3A current capability

for logic IC operation and processors while minimizing the

overall power dissipation.

• Pentium^®Processors

• PowerPC^™, AMD K5 and K6 processors

• Pentium support of GTL+ bus supply

• Low voltage logic supply

• Embedded Processor supplies

• Split plane regulator

Current limit ensures controlled short-circuit current. On-chip

thermal limiting provides protection against any combination

of overload and ambient temperature that would create exces-

sive junction temperatures.

• New 2.5V and 1.8V Logic Families

The FAN1582 series regulators are available in the industry-

standard 5-Pin TO-220 and TO-263 power packages.
