L4938E Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the L4938E is 26V, although it's recommended to keep it below 24V for reliable operation.
-
To ensure stability, make sure to use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of less than 1 ohm, and a minimum input capacitance of 1uF with an ESR of less than 5 ohms.
-
The L4938E can deliver up to 1.5A of output current, but this may vary depending on the input voltage, ambient temperature, and other factors. It's recommended to derate the output current to ensure reliable operation.
-
The output voltage of the L4938E can be adjusted by connecting a resistor divider network between the output and the ADJ pin. The output voltage is determined by the ratio of the resistors and the internal reference voltage.
-
Yes, the L4938E is AEC-Q100 qualified, which means it meets the requirements for automotive applications. However, it's essential to ensure that the device is used within its specified operating conditions and that the application meets the relevant automotive standards.
