LM25118MH/NOPB datasheet by Texas Instruments

LM25118MH/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM25118MH/NOPB?
  The maximum input voltage that can be applied to the LM25118MH/NOPB is 42V, but it's recommended to keep it below 40V for reliable operation.
• How do I ensure the stability of the output voltage in the LM25118MH/NOPB?
  To ensure stability, it's essential to use a minimum output capacitance of 10uF with an ESR of 1ohm or less, and to follow the recommended PCB layout guidelines.
• What is the maximum output current that the LM25118MH/NOPB can deliver?
  The LM25118MH/NOPB can deliver up to 2A of output current, but it's recommended to derate the output current based on the ambient temperature and the input voltage.
• How do I protect the LM25118MH/NOPB from overcurrent conditions?
  The LM25118MH/NOPB has a built-in overcurrent protection feature that limits the output current to 3.5A. Additionally, you can add an external current sense resistor to further limit the output current.
• What is the thermal shutdown temperature of the LM25118MH/NOPB?
  The thermal shutdown temperature of the LM25118MH/NOPB is 150°C. The device will shut down when the junction temperature exceeds this value, and will restart when the temperature drops below 130°C.
