MC7812CT Frequently Asked Questions (FAQ)

  • The MC7812CT can handle input voltages up to 35V, but it's recommended to keep it below 25V for reliable operation.

  • The MC7812CT can supply up to 1A of output current, but it's recommended to keep it below 0.5A for reliable operation.

  • The dropout voltage of the MC7812CT is typically around 2V, which means the input voltage should be at least 2V higher than the output voltage for proper regulation.

  • The MC7812CT 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.

  • To ensure stability, use a minimum output capacitance of 10uF and an input capacitance of 1uF or more. Also, keep the input and output capacitors close to the regulator to minimize noise and oscillation.
