L7912CV Frequently Asked Questions (FAQ)
-
The L7912CV can handle a maximum input voltage of 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 10uF, and keep the input and output capacitors close to the regulator. Also, use a low-ESR capacitor for the output.
-
The dropout voltage of the L7912CV is typically around 2V, which means the input voltage should be at least 2V higher than the output voltage for proper regulation.
-
The L7912CV 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 varistor in parallel with the input capacitor to protect the L7912CV from input voltage surges and spikes.
