The LM431BIZX is a three-terminal adjustable shunt voltage reference diode that features very high temperature stability and low output noise. It is available in 5-pin TO-220 package, and is pin compatible with LM185 series references. The LM431BIZX is a high-performance device, suitable for an extensive variety of precision processing, linear and switching power supply applications.

The LM431BIZX offers excellent spacing between the input and output voltage, typically 1.221V, to which it will keep with high accuracy even in the presence of large line transients of up to plus or minus 20V. Its superior gain temperature stability and low noise are due to the use of balancing techniques and proprietary burst switching current topping circuits.

The LM431BIZX provides a wide range of features for ease of use and performance improvement. It has an internal motor drive mode for fast switching between two voltage references and an adjustable internal trim current for fine tuning of the reference voltage range. The device can also be programmed via the I2C bus for enhanced precision control and programming flexibility. A fail-safe thermal shutdown circuit reduces the thermal stress on the LM431BIZX and prevents any potential damage.

The LM431BIZX is an ideal choice for a wide range of PMIC voltage reference applications, such as DC-to-DC converters, sensor amplification circuits and precision monitoring systems. Its high accuracy and performance features make it ideal for a wide range of industrial, automotive and consumer applications.

The LM431BIZX works according to the principle of conducting a current between its two external terminals, and passing the current through an internal resistor network. At this point, the current passing through the resistor network is proportional to the voltage difference between the two terminals. The voltage output of the device is then related to this current by its internal circuitry.

The LM431BIZX\'s internal logic provides the necessary function for the reference voltage range selection. This logic utilizes the internal current topping circuit to quickly switch the reference voltage range. By choosing the right reference voltage range, the user can precisely control the output voltage of the device.

The LM431BIZX also integrates an adjustable trim current, which helps to fine tune the output voltage of the device. This trim current is controlled by an external resistor, allowing the user to adjust the output voltage of the device to the desired level.

The LM431BIZX is an ideal choice for a wide range of PMIC voltage reference applications. Its high accuracy and performance features, low output noise and wide range of voltage references make it ideal for many industrial, automotive and consumer applications.
