... Application information The LM217M/LM317M provide an internal reference voltage of 1.25 V between the output and adjustment terminals. These devices are used to set a constant current flow across an external resistor divider (see ADJ 2. The devices were designed to minimize the term I constant in line and load changes. Usually, the error term I obtain the previous requirement, all the regulator quiescent current is returned to the output terminal, imposing a minimum load current condition ...
