Minimum VIN = VOUT + VDO or the value shown for Input voltage in this table, whichever is greater.

(2)

This device employs a leakage null control circuit. This circuit is active only if output current is less than pass transistor leakage

current. The circuit is typically active when output load is less than 5 μA, VIN is greater than 18 V, and die temperature is greater than

100°C.
