LM2937ET-15 Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LM2937ET-15 is 26V, but it's recommended to keep it below 24V for reliable operation.
-
While the LM2937ET-15 can handle up to 1A of output current, it's not recommended for high-current applications due to thermal limitations. For high-current applications, consider using a switching regulator or a more robust linear regulator.
-
To ensure stable and accurate output voltage, make sure to use a stable input voltage, decouple the input and output with capacitors, and keep the device within its recommended operating temperature range.
-
Yes, the LM2937ET-15 is qualified for automotive applications and meets the AEC-Q100 standard. However, ensure that the device is used within its recommended operating temperature range and that the input voltage is within the specified range.
-
The dropout voltage of the LM2937ET-15 is typically around 1.5V to 2V, depending on the output current. This means that the input voltage must be at least 1.5V to 2V higher than the output voltage for the regulator to operate properly.
