FAN1587A
3A Adjustable/Fixed Low Dropout Linear Regulator
• Fast transient response
• Low dropout voltage at up to 3A
• Load regulation typical
• Trimmed current limit
• On-chip thermal limiting
• Standard TO-220, TO-263, TO-263 center cut,
and TO-252 packages
• Class GTL+ bus supply
• Low voltage logic supply
• Post regulator for switching supply
• 12V to 5V linear regulator
• 3.3V to 1.5V linear regulator

The FAN1587A, FAN1587A-1.5, and FAN1587A-3.3 are low dropout three-terminal regulators with 3A output current capability. These devices have been optimized for low voltage applications including VTT bus termination, where transient response and minimum input voltage are critical. The FAN1587A is ideal for low voltage microprocessor applications requiring a regulated output from 1.5V to 3.6V with an input supply of 12V or less. The FAN1587A-1.5 offers 1.5V with 3A current capability for GTL+ bus VTT termination. The FAN1587A-3.3 offers 3.3V current capability for logic IC operation.

Current limit is trimmed to ensure output current and controlled short-circuit current. On-chip thermal limiting provides 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.
