When IC is stand alone, reduced by 8.0mW for each increase in Ta of 1 C over 25 C. When mounted on a

The built-in regulator in this IC outputs + 5.0V from pin 55, and - 5.0V from pin 59. The supply voltage range
given above is the voltage to be applied to UNREG V
obtain regulator output. Therefore, the upper limit of the voltage range is set by the externally connected
transistor that forms the regulator circuit, and not by the IC itself. Note, also, that the lower limit will change
depending on the value of the resistor connected between the collector and base of the transistor.
