... JA cessive die temperature, and the regulator will go into thermal shutdown. Note 4: If used in a dual-supply system where the regulator load is returned to a negative supply, the LP2980 output must be diode-clamped to ground. Note 5: The output PNP structure contains a diode between the V will turn on this diode (see Application Hints). ...

... ON/OFF INPUT OPERATION The LP2980 is shut off by pulling the ON/OFF input low, and turned on by driving the input high. If this feature is not to be used, the ON/OFF input should be tied to V regulator on at all times (the ON/OFF input must not be left floating) ...

... For best load regulation at the high load current, the LP2980 output voltage connection should be made as close to the load as possible. Although this regulator can handle a much higher load cur- rent than can the LP2980 alone, it can be shut down in the same manner as the LP2980. When the ON/OFF control is 14 DS012078-51 ...
