Part Number: LMC555
Hi team,
According to datasheet.

From the datasheet of LCM555, and it can work from 1.5 to 12V . and in the use example, only list 1.5 ,5V,12V three voltage. But my customer plan to apply VBAT=4.0V on Vs, if it is ok?

Hello Jason,
Yes, the LMC555 will operate between Vs = 1.5V to 12V with the Absolute maximum being 15V. It is ok to operate the device with Vs= 4V.
