Frequently Asked Questions
What is the dropout voltage of the LM2940CT-9.0/NOPB?
The LM2940CT-9.0/NOPB has a typical dropout voltage of 0.5V and a maximum of 1V at full 1A load. This low dropout characteristic means the input voltage only needs to be about 1V higher than the 9V output, making it suitable for battery-powered and automotive applications where input headroom is limited.
What is the input voltage range for the LM2940CT-9.0/NOPB?
The LM2940CT-9.0/NOPB accepts an input voltage from 10.5V minimum to 26V maximum, with an absolute maximum rating of 45V. This wide range makes it compatible with automotive 12V systems and other variable supply rails while providing protection against voltage transients up to 45V.
What are the typical applications for the LM2940CT-9.0/NOPB?
This regulator is commonly used in automotive electronics, industrial control boards, consumer appliances, and instrumentation requiring a regulated 9V supply. Its robust protection features — including thermal shutdown, current limiting, and reverse battery protection — make it particularly well-suited for harsh automotive environments and battery-powered designs.
Is the LM2940CT-9.0/NOPB RoHS compliant and lead-free?
Yes, the LM2940CT-9.0/NOPB is fully lead-free (Pb-free) and carries the JESD-609 e3 code, confirming RoHS compliance. It is suitable for designs requiring halogen-free and environmentally compliant components.
