REGULATOR
DESCRIPTION
The UTC
UZ1084-ADJ/Fixed
voltages 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.
