Frequently Asked Questions
What is the output voltage and maximum output current of the LM2940CS-9.0/NOPB?
The LM2940CS-9.0/NOPB provides a fixed 9V regulated output voltage with a maximum output current of 1A. The typical dropout voltage at full load is 0.5V, and the maximum dropout is 1V, making it suitable for applications where the input supply is only slightly above 9V.
What input voltage range does the LM2940CS-9.0/NOPB support?
The LM2940CS-9.0/NOPB operates with an input voltage range from 10.5V minimum to 26V maximum, with an absolute maximum rating of 45V. This wide input range makes it compatible with automotive 12V systems and other applications where voltage spikes may occur.
Is the LM2940CS-9.0/NOPB RoHS compliant and lead-free?
Yes, the NOPB suffix indicates this part is lead-free and RoHS compliant, manufactured without hazardous substances per EU RoHS directive. The device comes in a TO-263 (D-PAK) surface-mount package, offering excellent thermal performance for high-current applications.
What protection features does the LM2940CS-9.0/NOPB include?
The LM2940CS-9.0/NOPB includes internal current limiting to protect against output short circuits and thermal shutdown circuitry that activates when junction temperature exceeds safe limits. These features allow the device to recover automatically once fault conditions are removed, enhancing system reliability.
