What is the internally defined soft-start time for TI LDOs, for which soft-start is not available as a controllable feature?

Hi Sergei,

I am not personally familiar with LP2992; however, typically there will be a startup waveform or specification somewhere in datasheets.  For example, with TLV702 we specify startup time in the Electrical Characteristics table:

Do TLV702xx LDOs have monotonic rise to their steady state levels after being enabled via EN input?

Hi Sergei,

TLV702 has a monotonic rise.

Hello, Ryan!
Thank You for Your answer.
For TLV702 family I could not find that info in the datasheet.
But for the second LDO in question ( LP2992 ) the following screenshot from its datasheet shows, that it doesn't have monolitic rise. Is it really so?

Which LDO families have monotonic rise and which don't have?

Hi Sergei,

Any LDOs with a Soft-Start pin like TPS7A8300 or TPS74701 have a monotonic rise. Else, you'll have to look at the specific start-up graphs of the device in question as a monotonic start may not always be a prominent feature of lower current LDOs. As always, if you have a question about a particular device, feel free to shoot it our way.

Let me know if I can further assist,
