LM2940CT-5.0 Frequently Asked Questions (FAQ)
-
The maximum input voltage is 26V, but it's recommended to keep it below 20V for reliable operation.
-
The LM2940CT-5.0 is rated for operation up to 125°C, but thermal derating is required above 85°C. Ensure proper heat sinking and thermal management.
-
The output voltage tolerance is ±2% of the nominal output voltage (5.0V). So, the output voltage can be anywhere between 4.9V and 5.1V.
-
The minimum input voltage required for proper regulation is 7.5V, but it's recommended to keep it above 8V for optimal performance.
-
No, the LM2940CT-5.0 is a linear voltage regulator and not suitable for switching regulator applications. It's designed for low-dropout, low-noise, and high-PSRR applications.
