Hi TI Team,

I am looking for the low noise and Iq LDO and saw the TPS7A20 and TPS7A20L.

It stated that the TPS7A20L has a lower noise than the TPS7A20, however the webpage shows the same noise performance.

What is the difference in noise performance? Why would the TPS7A20L be better?

Thank you.

Kind regards,

Hey Wouter,

To clarify, the two devices have the same noise performance.

Please let us know where it is stated or where the confusion comes from, and we will have it updated.

I hope this helps!

Hi Jimmy,

The onepagers make it look like that, but that is clear.

What would be the difference of the L version vs non L version?

Kind regards,

Hey Wouter,

The only difference between the two devices is just the EN voltage thresholds.

The L version is JEDEC compliant with 1.2V I/O systems.

Hello Jimmy,

The L version will not replace the any other version of the TPS7A20, correct?

Thank you.

Kind regards,
