LM7815CT/NOPB datasheet by Texas Instruments

LM7815CT/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM7815CT/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 the recommended output capacitor (10uF) and input capacitor (0.33uF) values, and keep the input voltage at least 2V higher than the output voltage.
• What is the maximum current that the LM7815CT/NOPB can supply?
  The maximum output current is 1A, but it's recommended to keep it below 0.5A for reliable operation and to prevent overheating.
• How do I protect the LM7815CT/NOPB from overheating?
  Use a heat sink with a thermal resistance of 10°C/W or less, and ensure good airflow around the device. You can also use a thermal interface material to improve heat transfer.
• Can I use the LM7815CT/NOPB in a switching power supply?
  No, the LM7815CT/NOPB is a linear voltage regulator and is not designed for use in switching power supplies. It's intended for use in linear power supplies and battery-powered applications.
