L79L05ACZTR Frequently Asked Questions (FAQ)
-
The maximum input voltage is 35V, but it's recommended to keep it below 30V for reliable operation.
-
To ensure stability, a minimum output capacitance of 2.2uF is recommended, and the ESR (Equivalent Series Resistance) should be less than 5 ohms.
-
The dropout voltage is typically around 2V, which means the input voltage should be at least 2V higher than the output voltage for proper regulation.
-
The L79L05ACZ-TR is rated for operation up to 125°C, but the output current should be derated above 85°C to prevent overheating.
-
A TVS (Transient Voltage Suppressor) diode or a varistor can be used to protect the input of the L79L05ACZ-TR from voltage surges and spikes.
