LM78L09ACZ Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LM78L09ACZ is 35V, although it's recommended to keep it below 25V for reliable operation.
-
The LM78L09ACZ has a maximum operating junction temperature of 125°C, but it's recommended to keep it below 85°C for reliable operation. Above 85°C, the regulator's performance may degrade.
-
To ensure stability, use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of less than 5 ohms. Additionally, keep the input and output capacitors close to the regulator and use short leads to minimize inductance.
-
No, the LM78L09ACZ is designed to regulate positive voltages only. If you need to regulate a negative voltage, you'll need a different regulator or a voltage inverter circuit.
-
The LM78L09ACZ can deliver up to 100mA of output current, but it's recommended to keep it below 50mA for reliable operation.
