The LM4040AIX3-3.0+T, a device from Texas Instruments, is a micropower voltage reference. It is designed to provide a precision voltage reference output with a temperature coefficient of 3.0 ppm/C maximum. The device is conveniently packaged in an SOT-23-5 and an industry SOT-223 package. It is the ideal solution for battery-powered applications, and mobile communications applications requiring precision and reliability.

The LM4040AIX3-3.0+T works by using an improved low-noise perpendicular bipolar junction transistor (BJT) bandgap voltage reference cell to bias a commonly used CMOS process technology. The internal compensation technique eliminates the need for an external resistor, resulting in a much smaller figure of merit. This enables the low power consumption of the LM4040AIX3-3.0+T, making it the perfect choice for portable cellular and battery-powered systems.

The LM4040AIX3-3.0+T features a wide input voltage range of up to 6.5V. It eliminates the need for costly additional components such as bias resistors while providing a low temperature coefficient of 3.0 ppm/C maximum. It also features a guaranteed low current consumption, especially in the ON / OFF mode, with a minimum quiescent current of only 50μA (typical) at TA = +25°C. This makes it ideal for situation such as solar-powered applications or other battery-powered conditions where low power consumption is necessary.

The LM4040AIX3-3.0+T can be used in a variety of applications. It is particularly well-suited for metering and instrumentation, where it can be used to provide regulated and accurate level shifts. It is also ideal for digital regulators, where it can provide a stable and repeatable reference source. Additionally, it can also be used in transceiver applications for level-shifting and matching, as well as in mobile communications systems for noise suppression.
