L78M09CDT Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the L78M09CDT is 35V, although it's recommended to keep it below 30V for reliable operation.
  • To ensure stability, make sure to use a minimum output capacitance of 2.2uF, and a minimum ESR (Equivalent Series Resistance) of 0.5 ohms. Also, keep the input and output capacitors close to the regulator.
  • The minimum input voltage required for the L78M09CDT to regulate properly is around 10V, although it's recommended to keep it above 11V for reliable operation.
  • The L78M09CDT is rated for operation up to 150°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation.
  • To protect the L78M09CDT from input voltage transients, use a TVS (Transient Voltage Suppressor) diode or a varistor in parallel with the input capacitor to clamp the voltage.
