TL317CDRE4 datasheet by Texas Instruments

TL317CDRE4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TL317CDRE4 can handle?
  The TL317CDRE4 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 TL317CDRE4?
  The output voltage of the TL317CDRE4 can be adjusted by connecting a resistor divider network between the output and the adjust pin. The output voltage is determined by the ratio of the resistors and the reference voltage (1.25V).
• What is the minimum load current required for the TL317CDRE4 to regulate properly?
  The TL317CDRE4 requires a minimum load current of 3.5mA to regulate properly. If the load current is less than this, the output voltage may not be regulated accurately.
• Can I use the TL317CDRE4 in a high-temperature environment?
  The TL317CDRE4 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 TL317CDRE4 from input voltage transients?
  To protect the TL317CDRE4 from input voltage transients, it's recommended to add a transient voltage suppressor (TVS) diode or a zener diode between the input and ground. This will help to clamp the input voltage and prevent damage to the regulator.
