AMC7585
5A LOW DROPOUT REGULATOR
ELECTRICAL CHARACTERISTICS
Unless otherwise specified, V_IN = V_OUT + 2V, I_O = 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
