ELECTRICAL CHARACTERISTICS
Unless otherwise specified, these specifications apply over the operating ambient temperature of 0^OC to +70 ^OC for
AMC7584; I_O = 10mA, C_OUT = 10 µF, 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 2: Line and load regulation is 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: These parameters, although guaranteed, are not tested in production prior to shipment
