Part Number: LP5907-Q1

Hi Team,

There is a good new that we DIN LP590725QDQNRQ1

I want to confirm the following question

When the output voltage of LP590725QDQNRQ1 is 2.5V, the input voltage must be at least 3.5V, right? The specification is written like this,THX

    Hi Kygo,

    The maximum dropout at max load and across temperature is spec'd at 250mV, so normally all that would be required is to have VIN > VOUT + 0.25V under all operating conditions. However, since the datasheet specifies to use this LDO with VIN >= VOUT + 1V, that is what should be followed. That is not to say that it will not work with VIN < VOUT + 1V -- it may just be that there is some undesired behavior when this condition is not met.

    Regards,

    Nick
