Power supply voltage
The built-in regulator in this IC outputs + 5.0V from pin 55, and – 5.0V from pin 59. The power supply
voltage given above is the voltage to be applied to UNREG V
measurement circuit to obtain regulator output. Therefore, the upper limit of the power supply voltage
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.
When IC is stand alone, reduced by 8.0mW for each increase in Ta of 1 C over 25 C. When
mounted on a 90mm
each increase in Ta of 1 C over 25 C).
