Hi community,


I have a question about MMPF0100.

I want to know the behavior when VIN is under voltage of switching regulators or linear regulators output setting.

(e.g. VIN=3.0V, SW2=3.3V, VGEN3=3.3V)

I understand MMPF0100 goes into coincell mode when VIN < UVDET(2.65V), then how about when UVDET < VIN < Vout?

Vout = VIN in this case? or Vout is stopped?


Best Regards,
