UNISONIC TECHNOLOGIES CO., LTD UZ1084
5A ADJUSTABLE/FIXED LOW DROPOUT LINEAR REGULATOR
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. On-chip thermal limiting provides protection against any combination of overload and ambient temperature that would create excessive junction temperatures.
