Integrated Circuit
Adjustable Precision Shunt Regulator
Description:
The NTE999 is a three–terminal adjustable shunt regulator with guaranteed thermal stability over a
temperature range of –0° to +70°C. The output voltage may be set to any value between Vref (approxi-
mately 2.5V) and 36V with two external resistors. This device has a typical dynamic output imped-
ance of 0.2. Active output circuitry provides a very sharp turn–on characteristic, making the NTE999
an excellent replacement for zener diodes in many applications.
Features:
D Equivalent Full–Range Temperature Coefficient: 30ppm/°C Typ
D Adjustable Output Voltage
D Fast Turn–On Response
D Sink Current Capability: 1mA to 100mA
D Low Dynamic Output Impedance: 0.2Typ
D Low Output Noise Voltage
