Q: Tolerance on TPS71401 by 1585090
"Is the minimum internal reference voltage shown on the TPS71401 datasheet correct? Seems like it should be 1.16V rather than 1.12V. 1.12V is a -7% tolerance!
The TPS71501 works on paper… the only reason I didn’t use it is that I thought I could save money with the 71401. Can you tell me if the 71501 is the same basic design with improvements in variability, or is it a fundamentally different design that might behave differently? The issue is that I’ve done all my testing with the 71401. It seemed odd to me that the accuracy spec was so lopsided i.e. +4 -7% whereas the 71501 is +4 -4."

Yes, the datasheets are correct. The TPS71401 and TPS71501 ICs are very similar. The main differences between the TPS71401 and TPS71501 are 80mA vs 50mA and 10V input max vs 24V input max. The datasheet is correct and shows that the TPS71401 has a slightly wider tolerance than the TPS71501.
