DESCRIPTION
The AMC7585 is a high performance low dropout regulator
rated for 5A output current with fixed 2.5V/3.3V/5.0V and
adjustable output. It is designed for use in applications requiring
low dropout characteristics over the rated current range.
On chip trimming adjusts the reference voltage to 1%. These
features are ideal for low voltage microprocessor applications
www.DataSheet4U.croemquiring a regulated 2.5V to 3.6V power supply.
In addition, the AMC7585 provides the device protections
including over current and thermal shutdown. Also, reverse
battery protection scheme limits the reverse current when the
input voltage falls below the output.

5A LOW DROPOUT REGULATOR
ELECTRICAL CHARACTERISTICS
Unless otherwise specified, VIN = VOUT + 2V, IO = 10mA. These specifications apply operating ambient temperature
range, and are for DC characteristics only. (Low duty cycle pulse testing techniques are used which maintains
junction and case temperatures equal to the ambient temperature.)

Note 1 Output voltage is set to be 2.5V.
Note 2: Line and load regulations are guaranteed up to maximum power dissipation determined by input/output
differential and the output current. However, the maximum power will not be available over the full
input/output voltage range.
Note 3: The specifications represent the minimum input/output voltage required to maintain 1% regulation.
Note 4: The minimum load current is the minimum current required to maintain regulation. Normally the current in
the resistor divider used to set the output voltage is selected to meet the minimum load current requirement.
Note 5: These parameters, although guaranteed, are not tested in production prior to shipment
