Part Number: LP5912-Q1

LP5912Q1.5DRVRQ1  the Datasheet show that when Vin-Vout = 0.5V is the best status。But we want 1.8V in ,1.5V out， The performance is OK？The I-out = 350mA.

    Hi Lei,

    The part should not be in dropout at this current with this much headroom, but the part will be operating on the edge of dropout. In this state the PSRR and transient response of the LDO can be degraded. I would recommend testing the part with your transient specs and seeing if it will work for your application.

    Also, keep in mind all of the datasheet specifications are tested when Vin - Vout = 0.5V, if this condition is not met the specifications in the EC table are not guaranteed.

    Best Regards,
    Mark
