TL431AID Frequently Asked Questions (FAQ)
-
The recommended operating temperature range for TL431AID is -40°C to 125°C, although it can function up to 150°C with reduced performance.
-
To ensure stability, it's essential to add a compensation capacitor (typically 10nF to 100nF) between the REF and ADJ pins, and to keep the feedback loop impedance low.
-
The maximum allowed voltage on the REF pin is 36V, but it's recommended to keep it below 30V to ensure reliable operation.
-
Yes, TL431AID can be used as a voltage regulator, but it's not designed for high-current applications. It's suitable for low-power voltage regulation, such as in voltage references or low-power supplies.
-
The output voltage of TL431AID can be calculated using the formula: Vout = Vref * (1 + R1/R2), where Vref is the reference voltage (2.5V), R1 is the resistance between the REF and ADJ pins, and R2 is the resistance between the ADJ pin and ground.
