It is well-suited for use in precision measurement equipment, data converters, medical instrumentation, industrial process control, and low voltage power supplies.

Working Principle of the LM285Z-1.2/NOPB

The LM285Z-1.2/NOPB is an integrated circuit (IC) that uses a bipolar junction transistor (BJT) as its basic building block. A BJT is a type of transistor that uses two base terminals to control the current passing through it. The two base terminals are connected to two power grids through Resistors in order to control the voltage output by the device. The applied input voltage (Vin) generates a base current that is amplified and then used to drive a diode connected to the output terminal (Vout). The diode is placed in the reverse bias direction so that the voltage applied to it is limited by the reference voltage (Vref). The final output voltage is then determined by the ratio of Vref and the voltage applied to the input terminal (Vin).

Conclusion

The LM285Z-1.2/NOPB is a highly accurate, low power voltage reference device designed specifically for improved accuracy in power management applications. It features excellent temperature coefficient and noise performance and provides increased accuracy and reliability in precision circuits. The wide range of applications and the device’s ease of use make it a great choice for low power voltage reference designs.
