LSF0102-Q1: LSF0102-Q1 PIN2(VREF_A), PIN7(VREF_B), PIN8(EN) maximum rating current ((limited current) is?

Vref_A and Vref_B are identical with the other I/O channels, so the absolute maximum rating of 128 mA applies. But in most circuits, this does not matter because the current is limited by the 200 kΩ resistor.

EN is connected only to the gates of the pass transistors, so no current (except a very small leakage current) can flow.
