The TLV431ASN1T1G is an integrated voltage reference part from Texas Instruments, which is part of the company’s Power Management and Interface (PMIC) lineup. It is a medium voltage reference, with an accuracy of ±5% over the lifetime of the product.

The TLV431ASN1T1G is designed as a PTAT (Proportional to Absolute Temperature) reference. It provides stable, medium accuracy reference voltages over a wide range of temperatures, ranging from -25°C to 85°C. It is a three terminal voltage reference device, consisting of an external trim pin, an adjust pin and a reference output pin.

The external trim pin provides an adjustable reference voltage over the device’s lifetime. The adjustable pin is used to adjust the output voltage of the device to within the 5% accuracy. The reference output pin is driven by an internally generated reference voltage, which is dependent on the external temperature.

The TLV431ASN1T1G is useful in various applications that use PTAT voltage references. These applications include Digital-to-Analog Converters (DAC) for industrial automation, medical imaging and consumer audio/video applications. It is also useful in Systems-on-Chip (SoC) and embedded systems, as it provides a strongly temperature stable reference voltage.

The TLV431ASN1T1G is a solid choice for designing consumer electronic and industrial applications, where temperature drift of the reference voltage is important. By accurately controlling the output of the device, the effects of external temperature changes can be greatly minimized.

In sum, the TLV431ASN1T1G is an integrated voltage reference device that is designed for use in applications where accuracy and temperature stability of the reference voltage is important. It is a 3 terminal device, with an external trim pin, an adjustable pin and a reference output pin, and is useful for a variety of consumer and industrial applications.
