  • TPS7A90: Load transient

    Resolved
    Part Number: TPS7A90 Hi Our customer is comparing the competitor and TPS7A90 about load transient. The transients specification of competitor is very fast such as 1.5us(time to ouput voltage settle) at Io=1~500mA/Co=4.7uF. As I can see at figure 30, the…

  • RE: LP5912: LP5912 input voltage requirements

    Resolved
    Hi Sean, You are correct in that the output voltage will not fall so long as the input is at least VOUT + VDO. However, PSRR is affected by the proximity to dropout - operating closer to dropout reduces effective PSRR - so I would imagine that that is…
