LM117E/883 datasheet by Texas Instruments

LM117E/883 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM117E/883 can handle?
  The LM117E/883 can handle input voltages up to 30V, but it's recommended to keep the input voltage at least 2V higher than the output voltage to ensure proper regulation.
• How do I ensure the stability of the output voltage?
  To ensure stability, a minimum output capacitance of 10uF is recommended, and the ESR (Equivalent Series Resistance) of the capacitor should be less than 5 ohms.
• What is the maximum output current that the LM117E/883 can provide?
  The LM117E/883 can provide up to 1.5A of output current, but it's recommended to derate the output current based on the ambient temperature and input voltage.
• How do I protect the LM117E/883 from overheating?
  To prevent overheating, ensure good airflow around the device, and consider using a heat sink if the device is expected to operate at high temperatures or with high output currents.
• Can I use the LM117E/883 in a high-reliability or aerospace application?
  Yes, the LM117E/883 is a radiation-hardened device that meets the requirements of MIL-PRF-38535, making it suitable for use in high-reliability and aerospace applications.
