TL431ACLPR datasheet by Texas Instruments

TL431ACLPR Frequently Asked Questions (FAQs)

• What is the recommended operating temperature range for TL431ACLPR?
  The recommended operating temperature range for TL431ACLPR is -40°C to 125°C.
• How do I ensure stability when using TL431ACLPR in a voltage regulator circuit?
  To ensure stability, it's essential to use a compensation capacitor (Cc) between the Cathode and the Reference pins, and to follow the recommended PCB layout guidelines to minimize noise and oscillations.
• Can I use TL431ACLPR as a voltage reference in a high-temperature environment?
  Yes, TL431ACLPR is suitable for high-temperature environments. It has a low temperature coefficient, which ensures a stable voltage reference over a wide temperature range.
• What is the maximum allowed voltage on the Cathode pin of TL431ACLPR?
  The maximum allowed voltage on the Cathode pin of TL431ACLPR is 36V. Exceeding this voltage may damage the device.
• How do I calculate the output voltage of a voltage regulator circuit using TL431ACLPR?
  The output voltage (Vout) of a voltage regulator circuit using TL431ACLPR can be calculated using the formula: Vout = Vref * (1 + R1/R2), where Vref is the reference voltage (2.5V for TL431ACLPR), and R1 and R2 are the resistors in the voltage divider network.
