The maximum input voltage for the L78L33ACZ is 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 2.2uF, and keep the input capacitance as close to the regulator as possible. Also, use a low-ESR capacitor for the output.
The dropout voltage of the L78L33ACZ is around 2V, which means the input voltage should be at least 2V higher than the output voltage for proper regulation.
The L78L33ACZ is rated for operation up to 125°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 zener diode in parallel with the input capacitor to protect the regulator from voltage surges and spikes.
