TL431AQDBZR Frequently Asked Questions (FAQ)
-
The recommended operating temperature range for TL431AQDBZR is -40°C to 125°C.
-
To ensure stability, it's recommended to use a minimum output capacitance of 10uF and a minimum ESR of 0.1 ohms in the output capacitor. Additionally, a 1uF to 10uF capacitor can be connected between the REF and ADJ pins to improve stability.
-
The maximum allowed voltage on the REF pin is 36V. Exceeding this voltage can damage the device.
-
Yes, TL431AQDBZR is suitable for high-temperature environments. It has a low temperature coefficient of 20 ppm/°C, making it suitable for applications up to 125°C.
-
The output voltage of TL431AQDBZR can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the reference voltage (2.5V), R1 is the resistance between the output and the ADJ pin, and R2 is the resistance between the ADJ pin and ground.
