TL431IDR Frequently Asked Questions (FAQ)
-
The recommended operating temperature range for TL431IDR 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, and to place the capacitor close to the TL431IDR.
-
Yes, TL431IDR is suitable for high-temperature environments, but its voltage reference accuracy may degrade at temperatures above 100°C. It's recommended to use a voltage reference with a tighter tolerance, such as the TLV431, for high-temperature applications.
-
The output voltage of a TL431IDR-based voltage regulator can be calculated using the formula: Vout = Vref x (R1 + R2) / R2, where Vref is the reference voltage (2.5V for TL431IDR), R1 and R2 are the resistors in the voltage divider network.
-
TL431IDR is designed for low-current applications (up to 100mA). For high-current applications, it's recommended to use a more suitable device, such as the TLV431 or a dedicated voltage regulator IC.
