Hi Phil,

TLV743P does not have built-in soft-start function. A similar device that has a soft-start function built-in is TLV755P. There are also ways that you can inplement soft-start functions using external components, see this link:

Hi Jason,

Thanks for your reply.

I am looking at Vin=3.3V, Vout=3.0V, Iout=<200mA with Enable & Soft Start features.

Do you have any cost competitive solution other than TLV755P?

Best Regards,

Phil
