    hello

    I've got 1.3-3.3V range for LDO's input voltage.

    How should i design the opamp, to give me desired gain and other spec
    under different power supply voltages?

    What voltage should i design it for.

    I did it for 1.3V but when i change Vin to 3.3V the AC gain drops very much

    regards
