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.
