L78L15ABD Frequently Asked Questions (FAQ)
-
The maximum input voltage for the L78L15ABD is 35V, but it's recommended to keep it below 30V for reliable operation.
-
To ensure stability, use a minimum output capacitance of 2.2uF with an ESR (Equivalent Series Resistance) of less than 5 ohms, and keep the input capacitor close to the regulator.
-
The dropout voltage of the L78L15ABD is typically around 2V, which means the input voltage should be at least 2V higher than the output voltage for proper regulation.
-
The L78L15ABD is rated for operation up to 125°C, but its performance may degrade at high temperatures. Be sure to check the datasheet for thermal derating information.
-
Use a TVS (Transient Voltage Suppressor) diode or a varistor in parallel with the input capacitor to protect the regulator from voltage surges and spikes.
