TL431ID Frequently Asked Questions (FAQ)
-
The minimum operating voltage for TL431ID is 2.5V, but it's recommended to operate it at 4.5V or higher for optimal performance.
-
To ensure stability, it's essential to decouple the TL431ID with a 10nF to 100nF capacitor between the REF and ADJ pins, and a 1μF to 10μF capacitor between the VCC and GND pins.
-
While TL431ID can be used as a voltage regulator, it's not recommended as it's primarily designed as a voltage reference. If you need a voltage regulator, consider using a dedicated voltage regulator IC like the 78L05 or similar.
-
The TL431ID is rated for operation from -40°C to 125°C, but the accuracy and stability of the voltage reference may degrade at extreme temperatures.
-
The output voltage of TL431ID can be calculated using the formula: Vout = 2.5V x (1 + R1/R2), where R1 and R2 are the resistors connected between the REF, ADJ, and VCC pins.
