LDO Spec Question

Other Parts Discussed in Thread: TPS7A6650H-Q1, TPS7A19

Hi Team,

Why some TI's LDO D/S not show output noise(uVrms)? such as TPS7A19 and TPS7A6650H-Q1 etc.

    Hi Kuo,

    For these LDOs the noise was not a critical feature of the device they are more concerned with the wide input and output voltage range and high current in the case of the TPS7A19. As a result of the output voltage noise not being a critical specification these LDOs exhibit a large output noise >100uVrms, so it was not listed in the datasheet.

    Best Regards,
    Mark
