L78L12ACD Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the L78L12ACD 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 lead length between the regulator and the capacitors as short as possible.

  • The maximum output current that the L78L12ACD can deliver is 1.5A, although it's recommended to keep it below 1A for reliable operation.

  • To protect the L78L12ACD from overheating, make sure to provide adequate heat sinking, and keep the junction temperature below 125°C. You can also use a thermal shutdown circuit to turn off the regulator if it overheats.

  • No, the L78L12ACD is a linear regulator and is not designed for switching regulator applications. It's intended for use in linear power supplies and other applications where a fixed output voltage is required.
