2. 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.
3. This parameter is guaranteed by design and is not 100% production tested.
4. Dropout voltage is defined as the minimum input/output voltage differential required to maintain 1.5% regulation.
5. This parameter is guaranteed by design, but not parametrically tested in production. However, a 100% thermal shutdown functional test is
performed on each part.
