TL431ACLPRA Frequently Asked Questions (FAQ)
-
The recommended operating temperature range for TL431ACLPRA is -40°C to 125°C. However, it's essential to note that the device's performance may vary outside the typical operating temperature range of 0°C to 70°C.
-
To ensure stability, it's crucial to follow the recommended layout and component selection guidelines. This includes using a low-ESR capacitor, minimizing the distance between the TL431ACLPRA and the capacitor, and avoiding parasitic inductance in the circuit.
-
The maximum allowed voltage on the REF pin of TL431ACLPRA is 36V. Exceeding this voltage may damage the device or affect its performance.
-
While the TL431ACLPRA can be used as a voltage regulator, it's not its primary function. The device is designed as a programmable precision reference voltage source. If you need a voltage regulator, consider using a dedicated voltage regulator IC.
-
The output voltage of the TL431ACLPRA can be calculated using the formula: Vout = Vref * (1 + R1/R2), where Vref is the reference voltage (2.495V typical), R1 is the resistance between the OUT and ADJ pins, and R2 is the resistance between the ADJ and GND pins.
