L78M05CP Frequently Asked Questions (FAQ)

  • The maximum input voltage for the L78M05CP is 35V, but 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 keep the input capacitance as close to the regulator as possible. Also, use a low-ESR capacitor for the output.

  • The dropout voltage of the L78M05CP is around 2V, which means the input voltage should be at least 2V higher than the output voltage for proper regulation.

  • The L78M05CP is rated for operation up to 125°C, but its performance may degrade at high temperatures. Make sure to derate the output current and consider using a heat sink if operating in high-temperature environments.

  • Use a TVS (transient voltage suppressor) diode or a varistor in parallel with the input to protect the regulator from voltage surges and spikes.
