or the value shown for Input voltage in this table, whichever is greater.
(2) See Figure 1. The TPS715xx 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.
