UNISONIC TECHNOLOGIES CO., LTD UR533
5A ADJUSTABLE/FIXED ULTRA LOW DROP-OUT LINEAR REGULATOR
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.
