The TLV431AIDRE4 is a part of the series of adjustable voltage references within the PMIC - Voltage Reference product line. It is a family of voltage references featuring a high accuracy, low noise, and low temperature coefficient as a cost-effective solution for a variety of applications.

Applications of the TLV431AIDRE4 can include but are not limited to: battery management systems, digital one-shot, programmable gain amplifiers, and DC/DC converters. Besides its wide range of uses, it is particularly suitable for precision systems requiring low current operation of discontinuous mode.

The TLV431AIDRE4 offers a feedback resistor ratio from as low as 0.5V to as high as 36V. This is primarily driven by its external regulated adjustable resistor, adjustable over a range of 0.4 to 0.97V. This allows for setup of a wide range of output voltages all without the need for additional circuitry. The TLV431AIDRE4 also offers very good temperature drift which is 3ppm/°C and very low on-state current of 1μA.

The TLV431AIDRE4 accurately maintains a 2.5V reference voltage while providing a wide range of programmable output voltages between 0.5V to 36V. This reference output voltage is extremely stable, with a total accuracy of ±1mV over all operating ranges. Additionally, it features a fast transient response and low total harmonic distortion and can easily be adjusted during the design process.

The TLV431AIDRE4 is a burst mode device, meaning it can easily be cycled on and off to save power and provide a better system operating temperature. When the device is operating, it draws a maximum quiescent current of 3µA. By reducing the current to just 1µA and switching to burst mode when idle, the device helps conserve power.

The TLV431AIDRE4 is ideal for applications such as automotive, industrial and consumer, to name a few. In the automotive field, it can be used for many different applications such as ECU for engine management, antilock brakes, transmission control, and body electronics, to mention a few. It can also be employed in consumer applications such as audio systems, medical equipment, charging systems and other consumer accessories.

On the other hand, when employed in industrial applications, the TLV431AIDRE4 offers advantages like being easy to set up and use; providing a stable reference voltage; being compatible with a variety of devices; and, having a low current draw. This is perfect for any low-power industrial application.

In conclusion, the TLV431AIDRE4 is a voltage reference offering capabilities attractive to many different applications. It is adjustable over a range of 0.4 to 0.97V and is capable of providing a wide range of output voltages between 0.5V to 36V. It is low power, accurate and its temperature drift is 3ppm/°C. The TLV431AIDRE4 is ideal for automotive, industrial and consumer applications.
