Hey everybody. I'm new to the forum.
I have a electronic analog clock movement we manufacture. The motor drive we buy has started to not drive the second hand on initial startup. I measured 2.9 VDC out of the 3.3 regulator. I lowered the resistor from 1KΩ to 540Ω and now the hand starts as it should.
Finally my question: I now have 11 VAC driving the 3.3 regulator, if I am reading the data sheet (attached) correctly the regulator can handle 30 V input. Am I understanding the data sheet correctly?
Would the change from about 5 VAC to 11 VAC input significantly shorten the life of the regulator?
Thanks for your input.
