DESCRIPTION
The UTC UR533 is ultra-low dropout regulators with 5A output
current capability. This device has been optimized for low voltage
applications including VTT bus termination, where transient
response and minimum input voltage is critical. The UTC UR533 is
ideal for low voltage microprocessor applications requiring a
regulated output from 1.3V ~ 5.7V with a power input supply of
1.75V ~ 6.5V.
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.
