LM397MFX/NOPB Frequently Asked Questions (FAQ)
-
The maximum input voltage for the LM397MFX/NOPB is 42V, but it's recommended to keep it below 40V for reliable operation.
-
The LM397MFX/NOPB has an operating junction temperature range of -40°C to 125°C, but it's recommended to keep it below 85°C for reliable operation. Above 85°C, the regulator's performance may degrade.
-
To ensure stability, use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of less than 5 ohms. Additionally, keep the input capacitance as close to the regulator as possible.
-
The minimum input voltage required for the LM397MFX/NOPB to regulate the output voltage is around 7.5V, but it's recommended to keep it above 8V for reliable operation.
-
No, the LM397MFX/NOPB is a linear voltage regulator and not suitable for switching regulator applications. It's designed to provide a stable output voltage in linear mode.
