Note: LP3906 The default Power on delays can be reprogrammed at final test to 0, .5, 1, 2, 5, or 10 ms. Default setting is the same as the on sequence.
Power-On-Reset
The LP3906 is equipped with an internal Power-On-Reset
(“POR”) circuit that will reset the logic when VDD < V
POR. This
guarantees that the logic is properly initialized when VDD ris-
es above the minimum operating voltage of the Logic and the
internal oscillator that clocks the Sequential Logic in the Con-
trol section.
