TL780-12CKCE3 datasheet by Texas Instruments

TL780-12CKCE3 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TL780-12CKCE3?
  The maximum input voltage that can be applied to the TL780-12CKCE3 is 35V, but it's recommended to keep it below 25V for reliable operation.
• How do I ensure the TL780-12CKCE3 is stable and doesn't oscillate?
  To ensure stability, make sure to use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of less than 5 ohms, and a minimum input capacitance of 0.1uF.
• What is the dropout voltage of the TL780-12CKCE3?
  The dropout voltage of the TL780-12CKCE3 is typically around 2V, which means the input voltage must be at least 2V higher than the output voltage for proper regulation.
• Can I use the TL780-12CKCE3 in a high-temperature environment?
  The TL780-12CKCE3 is rated for operation up to 125°C, but its performance may degrade at high temperatures. Be sure to check the datasheet for thermal derating information and consider using a heat sink if necessary.
• How do I protect the TL780-12CKCE3 from input voltage transients?
  To protect the TL780-12CKCE3 from input voltage transients, use a TVS (Transient Voltage Suppressor) diode or a zener diode with a voltage rating higher than the maximum input voltage, and place it in parallel with the input capacitor.
