TPS7A84A: Schematic review for TPS7A84A

Part Number: TPS7A84A


Hi team we are using TPS7A8400A to generate 1V from 1.5V . I have attached the image which  shows the connections of the regulator. I request you to review the connections.

The output capacitors are of 0805 package

    Hi Keerthana, 

    With TPS7A8400A, the output can be generated with the ANY-OUT format:

    If the feedback network is better for your application, the recommended values are as followed:

    It is recommended that R1 is at least 12.4k to optimize noise and PSRR. The combination in your schematic does give Vout=1.001V, however it is worth mentioning the recommendations. 

    Overall, the schematic looks fine, they have followed the suggestion of capacitor size and type of 0805 ceramic capacitors, and even the 47||10||10 combination. 

    Lastly, I noticed the schematic says current= 3A, is this the intended load? If resistive load is used, make sure to use the correct value and wattage rating. i.e 0.333ohms and something that can withstand 3W. 

    Best,
