TL431CDR Frequently Asked Questions (FAQ)
-
The recommended operating temperature range for TL431CDR is -40°C to 125°C.
-
To ensure stability, use a minimum output capacitance of 10uF, and ensure that the output capacitor is placed close to the TL431CDR. Additionally, use a low-ESR capacitor and avoid using ceramic capacitors.
-
The maximum allowed voltage on the REF pin is 36V. Exceeding this voltage can damage the device.
-
Yes, TL431CDR is suitable for high-temperature environments. However, the voltage reference accuracy may degrade at high temperatures. Consult the datasheet for temperature-related specifications.
-
The output voltage (Vout) can be calculated using the formula: Vout = Vref * (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.
