TL317CD datasheet by Texas Instruments

TL317CD Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TL317CD can handle?
  The TL317CD can handle input voltages up to 40V, but it's recommended to keep the input voltage at least 2V higher than the output voltage to ensure proper regulation.
• How do I adjust the output voltage of the TL317CD?
  The output voltage of the TL317CD can be adjusted by using a resistor divider network between the output and the adjust pin. The ratio of the resistors determines the output voltage.
• What is the minimum load current required for the TL317CD to regulate properly?
  The TL317CD requires a minimum load current of 10mA to regulate properly. If the load current is less than 10mA, the output voltage may not be regulated accurately.
• Can I use the TL317CD in a high-temperature environment?
  The TL317CD is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and voltage at high temperatures to ensure reliable operation.
• How do I protect the TL317CD from input voltage transients?
  To protect the TL317CD from input voltage transients, it's recommended to use a voltage clamp or a transient voltage suppressor (TVS) diode at the input of the regulator.
