TL431BQDBZR Frequently Asked Questions (FAQs)
What is the recommended operating temperature range for the TL431BQDBZR?
The recommended operating temperature range for the TL431BQDBZR is -40°C to 125°C.
How do I ensure stability when using the TL431BQDBZR in a voltage regulator circuit?
To ensure stability, it's recommended to use a minimum output capacitance of 10uF and a maximum equivalent series resistance (ESR) of 1 ohm. Additionally, a 1uF to 10uF bypass capacitor between the REF and ADJ pins can help improve stability.
What is the maximum allowed voltage on the REF pin?
The maximum allowed voltage on the REF pin is 36V. Exceeding this voltage can damage the device.
Can I use the TL431BQDBZR as a voltage reference in a high-temperature environment?
Yes, the TL431BQDBZR is suitable for high-temperature environments. However, the voltage reference accuracy may degrade at high temperatures. It's recommended to use a voltage reference with a tighter tolerance and a lower temperature coefficient for high-temperature applications.
How do I calculate the output voltage of the TL431BQDBZR?
The output voltage of the TL431BQDBZR can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (2.5V), R1 is the resistance between the OUT and ADJ pins, and R2 is the resistance between the ADJ and GND pins.
What is the recommended operating temperature range for the TL431BQDBZR?
The recommended operating temperature range for the TL431BQDBZR is -40°C to 125°C.
