NOTE 1: For GS1085L(adjustable) VADJ=0V

NOTE 2: For the adjustable device 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 3 : The specification represent the minimum input/output voltage required to maintain 1% regulation.
