52840 REG0 Voltage Accuracy

[dgutierrez]

From the product spec, the voltage accuracy is listed as -10, +5% from the programmed value.  We're using 3.0 V.  For our application I need some more specifics on this regulator.  We're only using the LDO, and not the DC/DC.

Does this mean that on one unit that rail can vary over 2.7-3.15 V?

Is this variation expected to be a static offset unit-to-unit across a population, over time, over temperature, under load, or something else?

Lastly, what type of load and line regulation could we expect to see from this regulator?

Thanks in advance.

I'm looking for similar information.  Does the voltage accuracy change if you are using the LDO vs. DC-DC?  Are the max/min tied to temperature, etc.  The listed accuracy range is fairly large, so it does create some challenges as listed.  Any clarification would be great.

Hi, 

There is currently summer holiday in Norway so staffing is low, expect some delayed response time.

Hi

I just wanted to let you know that an internal ticket has been created to get an accurate reply for this case. Hopefully I'll be able to get back to you some time this week with an accurate answer. As of now, I only have a preliminary "guesstimate". I think the accuracy stated in the PS is correct, and that the output may vary over these values. I'm sorry about the delayed replies, but we're still low on staff.

Best regards,

Simon

OK.  Just to clarify, I'm not asking if the accuracy in the PS is accurate, but more details on what the variation is from.

Does this mean that on one unit that rail can vary over 2.7-3.15 V?

Is this variation expected to be a static offset unit-to-unit across a population, over time, over temperature, under load, or something else?

Lastly, what type of load and line regulation could we expect to see from this regulator?

Yes, this is what I am waiting for a clarification on from the developers/in-house experts. Thank you for your patience!

Best regards,

Simon
