ADS8900B: Question for ADS8900B Reference Design TIDA-01351 LDO Voltage Design

Part Number: ADS8900B
Other Parts Discussed in Thread: TPS7A88, , TIDA-01351

Hi Team,

Our is evaluating our ADS8900B reference design TIDA-01351, there is one LDO using TPS7A88 for +6V to 5.3V power supply converter. But if you are looking at TPS7A88's datasheet, the recommended maximum output voltage is only 5V. Whta's the design considerations in here to exceed TPS7A88's specification? Is it OK to use 5V instead of 5.3V in here?

Thanks.

    Jacky, hello and good day. The original design is no longer with us, so I'm going to reach out to the Industrial Systems Medical Team to determine who will assume responsibility for this design and can answer your question.  Please give me a day to identify the right team resource.
