Note 3:

The specification represents the minimum input/output voltage required to maintain 1% regulation.

Note 1:

For GS1185L(adjustable) VADJ=0V

For the adjustable device the minimum load current is the minimum current required to maintain

regulation. Normally the current in the resisto

meet the minimum load current requirement.
