The device is designed to min. the term IADJ (100uA max) and to maintain it very constant with line and load charges. Usually, the error term IADJ*R2 can be neglected. To obtain the previous requirement, all the regulator quiescent current is returned to the output terminal, imposing a min. load current condition. If the load is insufficient, the output voltage will rise. The SMLM317L is a floating regulator, input-output differential voltage,supplies of very high voltage with respect to ground can be regulated as long as the max. input-output differential is not exceeded. Furthemore, programmable regulators are easily obtainable and, by connecting a fixed resistor between the adjustment and output, the device can be used as a precision current regulator.
