TL431AIDR Frequently Asked Questions (FAQ)
-
The recommended operating temperature range for TL431AIDR 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 filter network.
-
Yes, TL431AIDR is suitable for high-temperature environments, but its voltage reference accuracy may degrade at temperatures above 100°C.
-
The maximum allowed voltage on the REF pin is 36V, but it's recommended to keep it below 30V for reliable operation.
-
The output voltage can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the reference voltage (2.5V), R1 is the resistor connected between the output and the adjust pin, and R2 is the resistor connected between the adjust pin and ground.
