L7912ACV Frequently Asked Questions (FAQ)

  • The L7912ACV can handle a maximum input voltage of 35V, but it's recommended to keep it below 25V for reliable operation.

  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and keep the input and output capacitors close to the regulator. Also, use a low-ESR capacitor for the output capacitor.

  • The L7912ACV requires a minimum input voltage of 14.5V to regulate properly and maintain a stable output voltage of 12V.

  • The L7912ACV is rated for operation up to 150°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 voltage clamp at the input to protect the L7912ACV from voltage surges and spikes.
