LM7915CT/NOPB datasheet by Texas Instruments

LM7915CT/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM7915CT can handle?
  The maximum input voltage for the LM7915CT 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?
  To ensure a stable output voltage, make sure to use a minimum of 10uF capacitor at the input and output pins, and keep the input voltage at least 2V higher than the output voltage.
• What is the maximum current that the LM7915CT can supply?
  The LM7915CT can supply up to 1A of current, but it's recommended to keep the current below 500mA for reliable operation and to prevent overheating.
• How do I protect the LM7915CT from overheating?
  To prevent overheating, make sure to provide adequate heat sinking, such as a heat sink or a metal core PCB, and keep the device in a well-ventilated area.
• Can I use the LM7915CT in a switching power supply?
  No, the LM7915CT is a linear voltage regulator and is not suitable for use in switching power supplies. It's designed for use in linear power supplies only.
