LM109H Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM109H is 30V, but it's recommended to keep it below 25V for reliable operation.
  • To ensure stability, use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of less than 5 ohms, and a minimum input capacitance of 1uF with an ESR of less than 10 ohms.
  • The minimum input voltage required for the LM109H to regulate properly is 7.5V for a 5V output, and 10.5V for a 12V output.
  • The LM109H is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and input voltage at high temperatures.
  • Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp to protect the LM109H from input voltage transients. A 1kΩ resistor in series with the input can also help to reduce the voltage spike.
