TPS7A6333-Q1 Low input voltage operation

I would like to confirm the operation with low input voltage.

In the case of 3.8V input voltage, how much is the accuracy of output voltage?

And doesn't the reset voltage reach in this case, do it?

We don't need the gurantee. We want to estimate the output accuracy with 3.8V input.

Hi Yamauchi-san,

Does the input voltage ramp down from higher voltage than 3.8V? Or just power up and be constant at 3.8V?

Dear Jason-san,

Could you please consider the input voltage ramp down?

Hi Yamauchi-san,

3.8V is about the boundary of the UVLO, if the input voltage ramp up from 0V, the device may not startup.
I am sorry we don't have ATE data about the accuracy of output voltage when input voltage fall down to 3.8V .
