differential and the output current. However, the maximum power will not be available over the full
input/output voltage range.
Note 3: The dropout voltage is measured by either minimum control voltage or power voltage. 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
Line and load regulations are guaranteed up to maximum power dissipation determined by input/output
