DESCRIPTION

The UTC UZ1084-ADJ/Fixed voltage are low dropout

three-terminal regulators with 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.

TO-263-3

On-chip thermal limiting provides protection against any

combination of overload and ambient temperature that would

create excessive junction temperatures.

TO-220F

ꢀ

FEATURES

*Fast transient response

*Pb-free plating product number: UZ1084L-xx

*Low dropout Voltage at up to 5A

*Load regulation : 0.5% typical

*On-chip thermal limiting

ꢀ

APPLICATIONS

*Desktop PCs, RISC and embedded processors’ supply

*GTI, SSTL logic Reference bus supply
