ISO1176T without LDO??

Other Parts Discussed in Thread: ISO1176T, SN6501

Hi,

is it possible, that the ISO1176T includes the SN6501?

Is it than also possible to use him without a LDO how you can do it with the SN6501 or is the voltage not stable enough?

Thank you for your help.

Andi,

You are correct that you can use the ISO1176T without an LDO, just like the SN6501.

Rgds,

Bryce

Hi Andreas,

Internal schematic ISO1176T and SN6501 is almost the same thus you could use them both without LDO if you have stable input voltage.

In other case be aware that bus side supply voltage for ISO1176T is in the range 4.75-5.25V (5V+-5%). Thus if your application have input voltage stability worth than 5% it is better to put LDO after rectifier.

Thanks for the answers. I also bought the Dev. Kit and the measure were successful :)

The output voltage is very stable. In my measure she is between 5,15@13mA and 5,01@92,6mA.

(Input voltage is constant at 4,97V.)
