Hi Sir,

after our review, we do not see any issue, do you have any suggestion or recommend change for this circuit? thanks for you support and learn from you.

    Hi Tommy,

    According to the datasheet, the bias rail needs at least a 10uF capacitor on it. The only thing I would be concerned about other than that is thermals as I'm not sure what your output current is. Operating at max output current for the part (3A) would give about a 31°C rise from ambient. I would also like to point out that using the larger CFF cap of 100nF does increase your start-up time. If that is not a concern then it's fine.

    Best, Aden
