Variable Output Voltage Regulator
(Dual Tracking Type)
Description:
The NTE7090 is a dual tracking, variable output voltage regulator housed in a 8–pin 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.
Features:
High Input voltage
Wide Range of Output Voltage
Low output noise voltage
Built–in current limiting and thermal shutdown circuit
The output voltage rise time constant of the coefficients can be adjusted by the value of the
external capacitor.
Capability of operation control by the external control signal (Pin 8).
