docid2168 rev 5 9/23 lm217l, lm317l application information 23 6 application information the lm317l provides an internal reference voltage of 1.25 v between the output and adjustments terminals. this is used to set a constant current flow across an external resistor divider (see figure 6. ), giving an output voltage v o of: v o = v ref (1 + r 2 /r 1 ) + i adj r 2 the device was designed to minimize the term i adj (100 a max) and to maintain it very constant with line and load changes. usually, the error term i adj r 2 can be neglected. to obtain the previous requirement, all the regulator quiescent current is returned to the output terminal, imposing a minimum load current condition. if the load is insufficient, the output voltage will rise. since the lm317l is a floating regulator and "sees" only the input-to-output differential voltage, supplies of very high voltage with respect to ground can be regulated as regulator as the maximum input-to-output differential is not exceeded. furthermore, 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. in order to optimize the load regulation, the current set resistor r 1 (see figure 6. ) should be tied as close as possible to the regulator, while the ground terminal of r 2 should be near the ground of the load to provide remote ground sensing.
