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

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.

FEATURES

* Ultra Low dropout voltage

* Remote sense operation

* Fast transient response

* Load regulation: 0.05% typical

* 0.5% initial accuracy

* On-chip thermal limiting
