UA78L12ACPK Frequently Asked Questions (FAQ)
-
The UA78L12ACPK 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 a minimum ESR (Equivalent Series Resistance) of 0.5 ohms. Also, keep the input and output capacitors close to the regulator.
-
The minimum input voltage required for the UA78L12ACPK to function properly is 14.5V, but it's recommended to keep it above 15V for reliable operation.
-
The UA78L12ACPK is rated for operation up to 125°C, but it's recommended to derate the output current at high temperatures to prevent overheating. Consult the datasheet for derating curves.
-
Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp at the input to protect the UA78L12ACPK from voltage transients and spikes.
