NTE999M
Integrared Circuit
Programmable Precision Reference

Description:
The NTE999M integrated circuit is a programmable shunt regulator in an 8-Lead DIP type package.
This monolithic IC voltage reference operates as a low temperature coefficient zener which is programmable from Vref to 36 volts with two external resistors. This device exhibits a wide operating current range of 1.0 to 100mA with a typical dynamic impedance of 0.22?. The characteristics of this
reference make it an excellent replacement for zener diodes in many applications such as digital voltmeters, power supplies, and op amp circuitry. The 2.5 volt reference makes it convenient to obtain
a stable reference from 5.0 volt logic supplies, and since the NTE999M operates as a shunt regulator,
it can be used as either a positive or negative voltage reference.

Features:
Programmable Output Voltage to 36 Volts
Voltage Reference Tolerance: ±1.0%
Low Dynamic Output Impedance: 0.22? Typical
Sink Current Capability of 1.0 to 100mA
Equivalent Full Range Temperature Coefficient of 50ppm/°C Typical
Temperature Compensated for Operation over Full Rated Operating Temperature Range
Low Output Noise Voltage.
