LM340T-15/NOPB datasheet by Texas Instruments

LM340T-15/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM340T-15/NOPB can handle?
  The maximum input voltage is 35V, but it's recommended to keep it below 25V for reliable operation.
• How do I ensure the output voltage is stable and regulated?
  Make sure to use a minimum of 10uF capacitor at the input and output pins, and ensure the input voltage is at least 2V higher than the output voltage.
• Can I use the LM340T-15/NOPB in a high-temperature environment?
  The LM340T-15/NOPB is rated for operation up to 125°C, but thermal derating is required above 85°C. Ensure proper heat sinking and thermal management to prevent overheating.
• How much current can the LM340T-15/NOPB supply?
  The LM340T-15/NOPB can supply up to 1.5A of output current, but it's recommended to keep it below 1A for reliable operation.
• Is the LM340T-15/NOPB short-circuit protected?
  Yes, the LM340T-15/NOPB has built-in short-circuit protection, which limits the output current to prevent damage in case of a short circuit.
