FAN1582

www.fairchildsemi.com FAN1582 3A Adjustable/Fixed Ultra Low Dropout Linear Regulator Features 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 5-Pin SPAK, TO-252 DPAK, and TO-263 packages Description 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 including VTT bus termination, where transient response and minimum input voltage are critical. The FAN1582 is ideal for low voltage microprocessor applications requiring a regulated 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 3A current capabilities for GTL+ bus VTT termination. The FAN1582-2.5 offers fixed 2.5V with 3A current capability for logic IC operation and processors while minimizing the overall power dissipation. Current limit ensures 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 FAN1582 series regulators are available in the 5-Pin SPAK, TO-252 DPAK, and TO-263 power packages.
