Note_1: All voltages are referenced to ground. Currents entering the device are specified positive, and currents exiting the device
are negative.
Note_2: This supply range guarantees that the LOAD voltage is not clamped by the overvoltage limit.
Note_3: Supply current specified with no load on the LOAD pin.
Note_4: Guaranteed by design; not production tested.
