FAN1084 4.5A Adjustable/Fixed Low Dropout Linear Regulator • Fast transient response • Low dropout voltage at up to 4.5A • Load regulation typical • On-chip thermal limiting • Standard TO-220, TO-263 center cut, and TO-252 packages • Desktop PCs, RISC and embedded processors’ supply • GTL, SSTL logic Reference bus supply • Low voltage VCC logic supply • Battery-powered circuitry • Post regulator for switching supply • Cable and ADSL modems’ DSP core supply • Set Top Boxes and Web Boxes modules’ supply Application Diagrams 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 VTT bus termination, where transient response and minimum input voltage are critical. The FAN1084 is ideal for low voltage microprocessor applications requiring a regulated output from 1.5V to 3.6A with an input supply of 5V or less. The FAN1084-1.5 offers 1.5V with 4.5A current capabilities for GTL+ bus VTT termination. The FAN1084-3.3 offers a 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 industrystandard TO-220, TO-263 center cut, and TO-252 DPAK power packages.

Application Diagrams

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 VTT bus termination, where transient response and minimum input voltage are critical. The FAN1084 is ideal for low voltage microprocessor applications requiring a regulated output from 1.5V to 3.6A with an input supply of 5V or less. The FAN1084-1.5 offers 1.5V with 4.5A current capabilities for GTL+ bus VTT termination. The FAN1084-3.3 offers a 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 industrystandard TO-220, TO-263 center cut, and TO-252 DPAK power packages.
