    Thanks for the introduction.
    Is there anything similar in the latest small size like the TPS series?

    We only have Adjustable Vout options in TPS series like TPS7A52, TPS7A92, TPS7A83 that can meet your 1.5/2A requirements. If you need fixed, the closest is TPS7A80 which has a max Iout of 1A.
