Q: TLV70231 dropout voltage at 250mA output by 6016

Hi,

in an application scenario a customer is looking for the dropout voltage of the TLV70231.

Vin = 3.25V - 3.45V, Iout = 250mA, Temp -40 to +85 Deg C, Vout = 3.1V +/-2%

The spec and graphs in the datasheet do not specifically cover this application scenario.

Could you please comment/feedback if such a low dropout could be achieved with the TLV70231 ?

The TLV70231 dropout voltage specification provides the maximum dropout over temperature with the operating conditions specified in the spec.  Because an LDO's dropout spec rarely defines dropout at a customer's exact operating conditions, we provide an appilcation note that helps the user calculate dropout at their conditions.  I have attached the link for your reference.
