... OUT SENSE Note 3: The dropout voltage for the AMS1501 is caused by either minimum control voltage or minimum power voltage. The specifications represent the minimum input/output voltage required to maintain 1% regulation. Note 4: 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 ...

... If power input comes up first the output will not turn on at all until the control voltage comes up. The output can never come up unregulated. By tying the control and power inputs together the AMS1501 can also be operated as a single supply device. In single supply operation the dropout will be determined by the minimum control voltage. ...
