Hi TI Teams,

Can u help to confrim that did TPS7A02 support 1.3V input and 1.2V output? If yes, how much conversion efficiency can be achieved at this time?

Thanks,

Kind Regards

    Hi Lumina, 

    Our current fixed output options for this part are: 1, 1.2, 1.5, 1.75, 1.8, 1.85, 2, 2.2, 2.3, 2.5, 2.8, 3, 3.1, 3.3, 3.6V.

    However, depending on what load the LDO is support, the 100mV headroom may not be enough. 

    As for efficiency, this app note helps define efficiency parameters for LDOS https://www.ti.com/lit/an/slva079/slva079.pdf

    Using the figures on page 8, you can better calculate the efficiency of your application.

    but I can't estimate that without the load. 

    Best,

    Juliette
