FAN1589

2.7A, 1.2V Low Dropout Linear Regulator for VRM8.5

Features

Description

• Fast transient response

The FAN1589 is a low dropout three-terminal regulator with

2.7A output current capability. This device has been optimized

for V bus termination, where transient response and mini-

• Low dropout voltage at up to 2.7A

• Load regulation: 0.05% typical

• Trimmed current limit

mum input voltage are critical. The FAN1589 offers ﬁxed

• On-chip thermal limiting

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

TO-252 (DPAK) packages

1.2V with 2.7A current capability for a GTL+ bus V

termination.

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.

Applications

• A GTL+ bus supply for VRM 8.5

• Low voltage logic supply

• Post regulator for switching supply

The FAN1589 is available in the industry-standard TO-220,

TO-263, TO-263 center cut and TO-252 (DPAK) power

packages.
