1 NTE999 Integrated CircuitAdjustable Precision shunt RegulatorDescription:The NTE999 is a three terminal Adjustable shunt regulator with guaranteed thermal stability over atemperature range of 0 to +70 C. The output voltage may be set to any value between Vref (approxi-mately ) and 36V with two external resistors. This device has a typical dynamic output imped-ance of . Active output circuitry provides a very sharp turn on characteristic, making the NTE999an excellent replacement for zener diodes in many :DEquivalent Full Range Temperature Coefficient: 30ppm/ C TypDAdjustable Output VoltageDFast Turn On ResponseDSink Current Capability: 1mA to 100mADLow Dynamic Output Impedance: TypDLow Output Noise VoltageAbsolute Maximum Ratings: (TA = 0 to +70 C unless otherwise specified)Cathode Voltage (Note 1), VKA37V.
