TPS7A14: How to program TPS7A14 for 0.6 V output?

John O'Brien
Prodigy 10 points
Part Number: TPS7A14
Other Parts Discussed in Thread: TPS7A10, TPS7A11

Page 1 of the TPS7A14 datasheet says:

Available in fixed-output voltages:
– 0.5 V to 2.05 V (in 25-mV steps)

However table 11.1.2 describes the device nomenclature as TPS7A14xx where xx is the nominal output voltage. Using this nomenclature the lowest voltage TPS7A14 available as an orderable part is TPS71A1408PYBKR i.e. 0.8 V output.

We need a 0.6 V output. We reached out to customer support and were told:

The TPS7A14 is capable of being programmed to output 0.6V. Having said that, please reach out to our product applications specialist, as this is a special request and there are other things we have to evaluate.  

Please can you help us understand how we can get a version of the TPS7A14 that supplies 0.6V output?

Thanks

John

    Hi John,

    These LDOs are fixed output devices where the setpoint is programmed at the factory.  It will take some time to fit something like this into our queue and we would need a business case to go fabricate these 0.6V version LDOs of the TPS7A14.  If you think you have a business case and the schedule, let me know.  Otherwise, can you let me know your key requirements and I can offer you some alternatives?  Will the TPS7A11 or TPS7A10 work?

    Thanks,

    Stephen

    Thanks for the quick reply Stephen. We are looking for a very small form factor regulator with 0.6V output. I think the TPS7A1006PYKAR may work, I will check with my team. Thank you for the help.

    Thanks John.  If you need the TPS7A14 then we'll want to discuss what your business case is.  We do not have the 0.6V version of the TPS7A14 right now, that would have to be created but if the business case is there we will certainly go do it.

    Thanks,

    Stephen

    Thanks Stephen, I think we can use the TPS7A10 but I will reach out again if we find this doesn't work. Thank you for the help!
