Hi Bonnie,

TPS82130 seems to meet your needs. Is something else needed?

Hi Chris,

Hi Bonnie,

You can add more output cap to reduce the ripple.

But I'm curious to see your measurement that shows the ripple is too high. Figure 23 shows less than 10 mV ripple. Your lower output voltages should be close to this value.
