L78M12CDT Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the L78M12CDT 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 input capacitance of 0.33uF. Also, keep the input and output capacitors close to the regulator and use short leads.

  • The maximum output current that the L78M12CDT can deliver is 1.5A, although it's recommended to keep it below 1A for reliable operation and to prevent overheating.

  • To protect the L78M12CDT from overheating, make sure to provide adequate heat sinking, such as a copper plane or a heat sink. Also, keep the ambient temperature below 50°C and ensure good airflow around the device.

  • No, the L78M12CDT is a linear voltage regulator and is not designed for use in switching regulator applications. It's intended for use in low-power, low-dropout applications where high efficiency is not required.
