It is also a precision programmable voltage reference that offers excellent accuracy, stability, reliability and cost-effectiveness. The TLV431BLPRM is a single device with integrated family of voltage references that provides a highly accurate voltage reference source with an output voltage ranging from 2.2V to 36V, allowing the user to select the most suitable output voltage to serve their application.

Application Field

The TLV431BLPRM family of voltage references is ideal for a wide range of applications. Its most prominent applications include power regulation, voltage control and voltage measurement. It is suitable for use in battery-powered systems due to its low power consumption and its excellent overall performance. The device\'s wide output voltage range makes it an ideal choice for automotive applications such as active filters. It is also suitable for applications that require a highly accurate voltage reference such as power supply design and instrumentation.

Working Principle

The TLV431BLPRM family of voltage references takes its name from the three-terminal structure that it uses to output its regulated voltage. This three-terminal structure consists of two regulated terminals (VOUT and VREF) and an adjustable control terminal (CTL). The VOUT terminal provides the regulated output voltage while the VREF terminal acts as a reference voltage that is equal to the output voltage. The CTL terminal is used to adjust the output voltage by adjusting the current in the circuit. The output voltage is determined by the applied current and the reference voltage at the CTL terminal.

The TLV431BLPRM has an on-chip voltage spike protector which is designed to protect the device from high switching currents or other input transient. It can also be used to protect the device from input overvoltage caused by non-load conditions, ensuring that the maximum output voltage is maintained.

The TLV431BLPRM is also equipped with an integrated temperature compensation function that allows the device to provide a more accurate and stable output voltage over a wide temperature range. This feature is particularly useful in automotive applications where an operating temperature range of -40°C to +125°C is a must.

The TLV431BLPRM Voltage Reference is a versatile, cost-effective and reliable voltage reference that is suitable for a wide range of applications. Its low dropout, wide output voltage range, integrated temperature compensation, and excellent accuracy make it an ideal choice for many situations.
