LM138K-MIL Frequently Asked Questions (FAQs)

  • The maximum input voltage for the LM138K-MIL is 40V, but it's recommended to keep it below 35V for reliable operation.
  • To ensure a stable output voltage, make sure to use a suitable input capacitor (e.g., 1uF) and output capacitor (e.g., 10uF) as close to the regulator as possible, and follow the recommended PCB layout guidelines.
  • The minimum input voltage required for the LM138K-MIL to function is 7.5V for the 5V output version, and 10.5V for the 12V output version.
  • The LM138K-MIL is rated for operation up to 125°C, but its performance may degrade at high temperatures. Ensure proper heat sinking and thermal management to maintain reliable operation.
  • Use a transient voltage suppressor (TVS) diode or a voltage clamp circuit to protect the LM138K-MIL from input voltage transients and spikes.
