TPS723: -1V Negative rail

Part Number: TPS723
Other Parts Discussed in Thread: TPS7A30

Hi team,

Do we have any negative LDO which can support -1V 100mA output?

TPS723 seems to be the closest one. 

Best,

Zeming

    Hey Zeming, 

    The TPS723 would work, but I would recommend using the TPS7A30 for some improved performance.
