LP5907: Aging/drift over time

Hi Steve,

Can you remind me again who the customer is? I don't see any long term drift data on this LDO.  LDO's typically do not have long term drift measurements, that is usually something you only see on the voltage references.   Having said that, we are initiating a long term drift station in our lab to capture these measurements for select LDO's.  We can look at adding this LDO to the testing however keep in mind it will take 1,000 hours, or 2,000 hours, or whatever - it's not a fast test.

Can you see if the customer will use the TPS7A20 or TPS7A21 instead?  Those are the modern version of the LP5907 which is now almost 15 years old.  The TPS7A20/1 is vastly improved upon the older LP59xx series, especially with compensation and transient response.  The newer device is also cheaper.  The LP5907 is still preferred in applications where incredibly fast turn on time is desired (and the inrush is not an issue).

Thanks,

Stephen

Hi Steve,

Also, please let me know if they need the -Q1 version of the LDO.  If you have opportunity details that would also help.

Thanks,

Stephen

I'll respond with customer via email shortly.
