... Figure 4. Circuit Since the 50 µA current from the adjustment terminal represents an error term, the LM350 was designed to minimize I this, all quiescent operating current is returned to the output establishing a minimum load current requirement. If there is insufficient load on the output, the output will rise. ...

... The discharge current depends on the value of the capacitor, the output voltage of the regulator, and the rate of decrease the LM350 this discharge path is through a large junction that is able to sustain 25 A surge with no problem. This is not true of other types of positive regulators. For output capacitors of 100 µ ...
