Electrical Characteristics (continued)

Notes:

() The “Output Voltage Tolerance” includes output voltage accuracy, voltage drift over temperature and the line regulation.

(2) The negative current means the current flows into the pin and the positive current means the current flows out from the pin.

(3) The thermal shutdown for both Channel A and B is independent from each other.
