The recommended input capacitor value is 1uF to 10uF, depending on the input voltage and output current requirements.
To ensure stability, use a minimum output capacitor of 10uF, and ensure the input capacitor is properly sized. Also, keep the input and output capacitors close to the regulator.
The maximum dropout voltage is 2V, which means the input voltage should be at least 2V higher than the output voltage.
The UA78L12ACPKG3 is rated for operation up to 125°C, but the maximum junction temperature is 150°C. Ensure proper heat sinking and thermal management to prevent overheating.
Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp to protect the regulator from input voltage surges and spikes.
