TPS76801 - Vout Accurancy

Hirotaka Matsumoto

Hello,

Would you mind if we ask Out Accurancy on TPS76801?

The data sheet shows following about Out Accurancy;

Conditions: –40°C＜ TJ＜ +125°C, VO + 1 V＜ VIN ＜ 10V, 10 mA＜ IO＜ 1A
OUT Accuracy : (0.98)VO＜VO＜(1.02)VO

<Question>
If we use TPS76801 on the condition which is small terms of use range as following,
how much value of OUT Accuracy you can except?

Conditions:0°C～65°C（TJ), VO+1V ＜ VIN ＜ VO+3V, 10mA ＜ IO ＜ 0.5A
OUT Accuracy : (???)VO＜VO＜(???)VO

If you have following characteristics, is it possbile to send us them?
- temperature dependance,
- input current dependence properties,
- output voltage dependence properties

Finally, if these contents are unofficial, could you send these replies to my E-mail address durectly?

We need your help.

Kind regards,

Hi Hirotaka,

The typical characteristics curves give an idea of how the output voltage is affected by current and temperature. While a smaller temperature range will likely yield tighter accuracy than the full operating temperature range, we are unable to give min/max guarantees on the accuracy.

Very Respectfully,

Ryan

Hi Ryan San,

Thank you for your prompt reply and your comment.

Ok, we understood your saying.
On the other hand, if you have dispersion of data about Vout accurancy,
could you send us these data?

Of cource, if these are unofficial, please send your reply to my E-mail address durectly.

kind regards,

Hi Hirotaka San,

We do not have any data outside of what is already in the datasheet to share. Please refer to the datasheet curves for an indication of how the device will behave under your conditions.

Very Respectfully,

Ryan
