(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to network ground terminal.

6.5 Electrical Characteristics
Over operating junction temperature range (TJ = –40°C to 125°C), VIN = VOUT(nom) + 1 V, IOUT = 1 mA, and COUT = 1 μF, unless otherwise noted. Typical values are at TJ = 25°C.

Figure 10. The TPS715 family employs a leakage null control circuit. This circuit is active only if output current is less than pass FET leakage current. The circuit is typically active when output load is less than 5 μA, V
IN is greater than 18 V, and die temperature is greater than 100°C.
