Electrical Characteristics:
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.
The V
ratio. The minimum value is equal to the quiescent current of the device.
This parameter is guaranteed by design and is not 100% production tested.
Dropout is defined as either the minimum control voltage, (V
required to maintain 1% regulation at a particular load current.
This parameter is guaranteed by design, but not parametrically tested in production. However, a 100% thermal shutdown functional test is
performed on each part.
