connected together. (See Pin Functions and Block Diagram for more detail.)
Note 3: Other channel turned OFF, i.e. AEN and BEN = 0V.
Note 4: The output is protected with fold-back current limit which reduces
the short-circuit (0V) currents below peak permissible current levels at
higher output voltages. (See Typical Performance Characteristics for
further detail on output current versus output voltage).
