The NTE7090 is a dual tracking, variable output voltage regulator housed in a 8pin SIP. The output voltage can be adjusted over a wide range from 3 to 30V by adjusting the value of the voltage setting external resistors. By adjusting the resistance of the external balance setting resistors the positive/negative output voltage ratio can also be set freely. Again by attaching power transistors high current gains can be achieved making the device suitable for use in the power supplies of a wide variety of equipment.
