Other Parts Discussed in Thread: TPS728, TPS780

Dear *,

Can you provide the part numbers for TI LDO that have a pin selectable voltage output?

We need 3.3V and 1.8V to be selected with GPIO pin.

Hello,

I'm looking at TPS728 part number that provide 3.3 and 1.8

This is the one TPS728330180YZU, and does the TPS728330185DRV also provide 3.3 and 1.8 or 3.3 and 1.85 ?

Which part number for TPS780 provides 3.3 and 1.8 ?

Best Regards,

David.

For TPS728, you are correct about TPS728330180YZU providing required voltage.

TPS728330185DRV is 3.3V and 1.85V.

For TPS780, it will have to be the adjustable versions that uses the Vset pin.
