TL431IZT Frequently Asked Questions (FAQ)
-
The TL431IZT can operate from -40°C to 150°C, making it suitable for a wide range of applications.
-
To ensure stability, it's essential to decouple the TL431IZT with a capacitor (typically 10nF to 100nF) between the REF and ADJ pins, and to use a low-ESR capacitor (e.g., ceramic or film) for the output capacitor.
-
To minimize noise and ensure proper operation, keep the TL431IZT away from high-current paths and noisy signals. Use a ground plane, and keep the input and output capacitors close to the device. Avoid using long traces and vias, and use a low-impedance path for the output.
-
The output voltage (Vout) of the TL431IZT can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (2.5V), and R1 and R2 are the resistors in the voltage divider network.
-
The typical current consumption of the TL431IZT is around 2.5mA, but this can vary depending on the output voltage and load conditions.
