LP8553 Operating input voltage range

masahiko shimizu

Hi,

Could you tell me about Operating input voltage range, please?

In datasheet of P1, input voltage range is shoewd 2.7V^22V at "FEATURE".
In datasheet of P5, input voltage range is shoewd 5.5V^22V at "Operating Ratings".

Which is correct?

Best regards,

Hello Shimizu,

Both are correct, but which one you should follow depends on the application. If you need below 5.5V input voltage range, you should use application diagram 2 as a reference. The 5.5V...22V range is for Application diagram1.

Hope this clarifies this.

Thanks.
