TL431CPKG3 Frequently Asked Questions (FAQ)
-
The recommended operating temperature range for the TL431CPKG3 is -40°C to 125°C.
-
To ensure stability, it's recommended to use a bypass capacitor (typically 10nF to 100nF) between the REF and ADJ pins, and to keep the impedance of the output circuit low.
-
The TL431CPKG3 can supply up to 15mA of output current, but it's recommended to limit the output current to 10mA or less to ensure stability and accuracy.
-
While the TL431CPKG3 can be used as a voltage regulator, it's not recommended due to its limited output current capability and lack of built-in current limiting. Instead, consider using a dedicated voltage regulator IC.
-
The output voltage of the TL431CPKG3 can be adjusted by connecting a resistor divider network between the REF and ADJ pins, and adjusting the ratio of the resistors to set the desired output voltage.
