L4975A Frequently Asked Questions (FAQ)
-
The L4975A can handle input voltages up to 40V, but it's recommended to keep it below 35V for reliable operation.
-
Choose an output capacitor with a low ESR (Equivalent Series Resistance) and a capacitance value between 10uF to 100uF. A 22uF capacitor is a good starting point.
-
The L4975A can operate with input voltages as low as 7V, but the output voltage regulation may not be guaranteed below 8V.
-
The L4975A is rated for operation up to 150°C, but it's recommended to derate the output current and input voltage to ensure reliable operation above 125°C.
-
The output voltage of the L4975A is determined by the resistor divider network between the output and the ADJ pin. Use the formula: Vout = 2.5V x (1 + R1/R2) to calculate the output voltage.
