Features

Description

• Fast transient response

The FAN1587A, FAN1587A-1.5, and FAN1587A-3.3 are low

dropout three-terminal regulators with 3A output current capa-

bility. These devices have been optimized for low voltage

• Low dropout voltage at up to 3A

• Load regulation: 0.05% typical

• Trimmed current limit

applications including V bus termination, where transient

• On-chip thermal limiting

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

and TO-252 packages

response and minimum input voltage are critical. The

FAN1587A is ideal for low voltage microprocessor applica-

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

input supply of 12V or less. The FAN1587A-1.5 offers ﬁxed

1.5V with 3A current capability for GTL+ bus V termina-

tion. The FAN1587A-3.3 offers ﬁxed 3.3V current capability

for logic IC operation.

Applications

• Pentium^®Class GTL+ bus supply

• Low voltage logic supply

• Post regulator for switching supply

• 12V to 5V linear regulator

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 FAN1587A, FAN1587A-1.5, and FAN1587A-3.3 are

available in the industry-standard TO-220, TO-263, TO-263

center cut, and TO-252 (DPAK) power packages.
