TL431IPK Frequently Asked Questions (FAQ)
-
The TL431IPK can operate from -40°C to 125°C, making it suitable for a wide range of applications.
-
To ensure stability, it's essential to decouple the TL431IPK with a 10nF to 100nF capacitor between the REF and ADJ pins, and a 1μF to 10μF capacitor between the VIN and GND pins.
-
The TL431IPK requires a minimum input voltage of 2.5V to function properly, but it's recommended to use a minimum of 4.5V for optimal performance.
-
While the TL431IPK is primarily a voltage reference, it can be used as a simple voltage regulator by adding an external resistor and transistor. However, it's not designed for high-current applications.
-
The TL431IPK has a typical voltage reference accuracy of ±1% over the entire operating temperature range, making it suitable for most applications requiring a stable voltage reference.
