LM140LAH-15/NOPB datasheet by Texas Instruments

LM140LAH-15/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM140LAH-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 stability of the output voltage?
  To ensure stability, use a minimum output capacitance of 10uF with an ESR of 5 ohms or less, and a minimum input capacitance of 1uF.
• What is the maximum current that the LM140LAH-15/NOPB can supply?
  The maximum output current is 1A, but it's recommended to keep it below 0.5A for reliable operation.
• How do I protect the regulator from overheating?
  Use a heat sink with a thermal resistance of 50°C/W or less, and ensure good airflow around the device.
• Can I use the LM140LAH-15/NOPB in a high-temperature environment?
  The device is rated for operation up to 125°C, but the output voltage may decrease at high temperatures. Use a heat sink and ensure good airflow to maintain reliability.
