LM285Z-1.2RA, which belongs to PMIC (Power Management ICs) - Voltage Reference, is developed by Texas Instruments to provide the input or output voltage reference which has good stability and accuracy under given operating temperature range. This article mainly focused on the insight of LM285Z-1.2RA, including its application field, workable environment and working principle, to help readers have a better understanding of this voltage reference device.

Application Field of LM285Z-1.2RA

The LM285Z-1.2RA is designed to be a temperature-stable and low-power voltage reference regulator. It provides a temperature-stable and low-power voltage reference with very good accuracy over a wide operating temperature range. It can be applied to circuits requiring stable and accurate output voltages, such as systems with microprocessors, data converters and other analog components.

The LM285Z-1.2RA has two output voltage modes: 1.2V and 1.4V. It can provide a stable, low-power and temperature-stable voltage reference of 1.2V or 1.4V (depending upon the output voltage mode) with a wide operating temperature range of -40°C to +125°C. The TTL or CMOS compatible shut down pin can be used to turn the device off when needed.

Workable Environment and Working Principle of LM285Z-1.2RA

The LM285Z-1.2RA is designed to function in an environment of 5V to 15V power supply and with an operating junction temperature range of -40°C to +125°C. It needs a good bypass capacitor and decoupling capacitor to properly function. The bypass capacitor usually have a voltage rating of at least 16V and 0.1uF, while the decoupling capacitor usually have a voltage rating of at least 16V and 0.01uF.

The working principle is that, when normal power and temperature condition is applicable, the LM285Z-1.2RA device draws a fixed input current from the power supply and directly regulates the output voltage as a constant and stable reference voltage. The regulated voltage depending on the output voltage mode, which can be 1.2V or 1.4V. The tolerance of output reference voltage is well within +/-1%.

Conclusion

The LM285Z-1.2RA belongs to PMIC (Power Management ICs) - Voltage Reference and serves as a temperature-stable and low-power voltage reference regulator. It is most applicable in circuits needing stabilized and accurate output voltages, such as systems with microprocessors, data converters and other analog components. It needs a good bypass capacitor and decoupling capacitor to correctly work and provide stable and precise reference voltage output in a wide operating temperature range.
