Diodes Incorporated TLV431AQFTA Voltage Reference

The TLV431AQFTA from Diodes Incorporated is a precision low-voltage shunt regulator that offers an excellent solution for adjustable voltage references in a variety of applications. This product is designed to be highly versatile and can be used in numerous power management tasks, including being part of a voltage monitor, an adjustable current source, or in a voltage reference in a wide range of consumer, industrial, and automotive products.

With a low output voltage range that spans from 1.24V to 16V, the TLV431AQFTA provides exceptional flexibility for designers. This is achieved through an adjustable V<sub>REF via resistors that are connected to the reference pin. The device features a typical temperature coefficient of merely 50ppm/°C, ensuring stable performance across a broad temperature range, which is crucial for applications requiring consistent operation under varying environmental conditions.

The TLV431AQFTA comes in a compact SOT-23 surface-mount package, making it ideal for space-constrained applications. It is characterized for operation from -40°C to +125°C, allowing it to be used in environments that experience extreme temperatures. Furthermore, the device boasts a low dynamic output impedance of 0.22 ohms, providing good transient response and noise rejection, which is highly beneficial for sensitive electronic circuits.

Another key feature of this voltage reference is its low minimum cathode current requirement of 1mA, which makes it suitable for low-power applications and contributes to energy efficiency in battery-operated devices. The TLV431AQFTA also includes an active output which can sink current, enhancing the regulator's versatility.

In summary, the TLV431AQFTA from Diodes Incorporated is a reliable and precise shunt voltage regulator that offers designers a high level of performance and flexibility. Its low temperature coefficient, adjustable output voltage, and low minimum operating current make it an excellent choice for a wide range of applications that require a stable and accurate voltage reference.
