Frequently Asked Questions
What is the output voltage range of the TL1431QD?
The TL1431QD provides an adjustable output voltage range from 2.5V (the internal reference voltage) up to 36V, with a maximum supply voltage of 37V. The output is set using an external resistor divider network connected to the reference pin.
What are typical applications for the TL1431QD?
The TL1431QD is commonly used in switching power supply feedback loops, linear regulator control, battery charger circuits, programmable voltage references, and over-voltage protection. Its high accuracy (0.4%) and wide voltage range make it suitable for industrial power conversion, consumer electronics, and telecom equipment.
How does the TL1431QD compare to the standard TL431?
The TL1431QD is a higher-grade variant with tighter initial accuracy of 0.4% compared to the standard TL431's 2% tolerance. It is offered in the 8-Pin SOIC (SOIC-8) package, providing the same core adjustable shunt reference functionality but with improved precision suitable for more demanding designs.
What package is the TL1431QD available in?
The TL1431QD is available in an 8-Pin SOIC (Small Outline Integrated Circuit) package, which is a surface-mount package well-suited for automated PCB assembly. The compact footprint makes it ideal for space-constrained designs in power management applications.
