Hello to everyone,

Is there an indication of min / max undervoltage lockout voltage from the TPS70933?

Thanks and best regards,

Hi Brian,

Unfortunately, the TPS709 does not have a well defined UVLO. We do guarantee that it will operate with VIN down to 2.7V. If VIN is below 3.3V, the device will do its best to regulate VOUT, but the output voltage will be VIN-ILOAD*RDSON (VDO or Drop-out is a function of load current time the effective RDSON of the FET).

I hope this answers your question.
