TL431ASDT,215 datasheet by NXP Semiconductors

TL431ASDT,215 Frequently Asked Questions (FAQs)

• What is the recommended operating temperature range for TL431ASDT,215?
  The recommended operating temperature range for TL431ASDT,215 is -40°C to 125°C.
• How do I ensure stability when using TL431ASDT,215 as a voltage reference?
  To ensure stability, it's recommended to use a bypass capacitor (e.g., 10nF) between the REF and ADJ pins, and to keep the impedance of the output circuit low.
• Can I use TL431ASDT,215 as a voltage regulator?
  While TL431ASDT,215 can be used as a voltage regulator, it's not recommended as it's primarily designed as a voltage reference. For voltage regulation, consider using a dedicated voltage regulator IC.
• What is the maximum output current of TL431ASDT,215?
  The maximum output current of TL431ASDT,215 is 15mA. Exceeding this limit may affect the device's accuracy and stability.
• How do I calculate the output voltage of TL431ASDT,215?
  The output voltage of TL431ASDT,215 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 external resistors.
