Part Number: TPS7A80

Hi Team，

Based on datasheet，it suggest 0.1uf-1uf，but want to check on if it is OK to use 1uf+10uf.

    Hi Given,

    Oversizing the capacitor is not going to be a problem for the circuit. Cin is not part of the stability control loop, so it will not cause the LDO to exit the stable operation.

    In fact on the datasheet on section 8.2.1.3. We discuss some situations in which you may need to upsize the input capacitor, in order to maximize the part's effectiveness.

    Regards,

    John
