Dear all:

     We need a LDO supprot +5V to -5V/100mA, Can TPS7A3401 support +5V  to -5V /100mA? or can you give some advise? thanks!

    Hi ,

    Unfortunately we do not have a linear regulator that can take a positive input voltage and generate a negative output voltage.  Please consider using an inverting buck-boost before the linear regulator to convert 5V to -6 V in order to provide enough headroom for the TPS7A3401 to achieve a regulated output at -5 V.

    Very Respectfully,

    Ryan
