2. This parameter is guaranteed by design and is not 100% production tested.

3. 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.

4. The control pin current is the drive current required for the output transistor. This current will track output current with roughly a 1:100 ratio.

The minimum value is equal to the quiescent current of the device.
