LM27762: Schematic and board layout review

Part Number: LM27762

Hi,

I am designing a wearable device that is to be powered by a LiPo battery. I will use a 3.3V converter for my micro-controller. However, my ADC and Op-Amp buffer will require a bipolar supply. I used the LM27762 and came up with the following design. I want to convert the 3.3V to ±2.5V.

Does this look OK or is there something I should change regarding the LM27762. I am already consulting the forum for my ADC and Op-Amp setup so those can be disregarded for now.

Let me know if there is anything to change regarding the TLV73333 as well. However, I have used that exact design successfully before.

    Hi Emil,

    I reviewed the schematic and layout for LM27762. Everything looks fine to me.

    TLV73333 falls under a separate product line. Could you please start a new thread for this part number.

    If you do not have any further questions, I will close this thread. Please hit "Resolved" if I resolved your problem.

    Regards,
