MIC2937A-3.3BU Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the MIC2937A-3.3BU is 26V, although it's recommended to keep it below 24V for reliable operation.
-
To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor (at least 10uF), and keep the input and output capacitors close to the device.
-
The minimum input voltage required for the MIC2937A-3.3BU to operate is 2.5V, although it's recommended to keep it above 3V for reliable operation.
-
The MIC2937A-3.3BU is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as temperature increases to ensure reliable operation.
-
The output voltage tolerance of the MIC2937A-3.3BU is ±2% over the entire operating temperature range. You can calculate the output voltage tolerance by multiplying the nominal output voltage (3.3V) by the tolerance percentage (2%).
