Frequently Asked Questions
What is the output voltage and current rating of the LM78M05CT/NOPB?
The LM78M05CT/NOPB provides a fixed 5V DC output with a maximum output current of 500mA (0.5A). Output voltage tolerance is ±4%, and it requires a minimum input voltage of 7.2V to maintain regulation.
What input voltage range does the LM78M05CT/NOPB support?
The device accepts an input voltage ranging from 7.2V (minimum for regulation) up to 35V absolute maximum. The typical dropout voltage is 1.8V, meaning input must exceed output by at least that margin for proper operation.
What package type and thermal protection does the LM78M05CT/NOPB have?
It comes in a TO-220 (Transistor Outline, Vertical) through-hole package, which allows easy heatsinking. The device includes built-in thermal shutdown and internal current limiting, protecting it from overtemperature and short-circuit conditions.
Is the LM78M05CT/NOPB RoHS compliant and lead-free?
Yes, the '/NOPB' suffix indicates the LM78M05CT/NOPB is fully RoHS compliant and manufactured without lead (Pb-free). Its JESD-609 code is e3, confirming it meets halogen-free and lead-free requirements for environmentally conscious designs.
