TL431ACPK Frequently Asked Questions (FAQ)
-
The recommended operating temperature range for TL431ACPK is -40°C to 125°C.
-
Yes, TL431ACPK can be used as a voltage regulator, but it's primarily designed as a programmable shunt regulator. It's not suitable for high-current applications.
-
Choose resistor values based on the desired output voltage and the reference voltage (2.5V). Use the formula: R1/R2 = (Vout - 2.5V) / 2.5V. Ensure the resistors are of suitable wattage and tolerance.
-
The cathode (K) pin is the output pin of the TL431ACPK. It's connected to the load and provides the regulated voltage.
-
No, it's not recommended to use multiple TL431ACPK devices in parallel to increase the current output. The device is not designed for high-current applications, and paralleling devices may lead to instability and reduced reliability.
