Other Parts Discussed in Thread: TPS7A66-Q1

Hi Linear Regulators team.

Can we use Input-Voltage-Sensing option TPS7A66xx and TPS7A69xxx as a below?

I watch TPS7A66xx typeical application on datasheet as a below

However, We want Voltage distribution like TPS7A69xx Typical Application schematics as a below

Can we use like TPS7A69xx voltage distribution at the TPS7A66xx-Q1?

If you have any question. anytime contact me.

Best Regards

Hi Gerald,

I am not sure what you mean by "voltage distribution." Do you mean that you would like to use a voltage divider (resistor divider) on EN for TPS7A66-Q1? You are able to use a resistor divider from Vin to reduce the voltage going to EN.

Very Respectfully,
Ryan

Hi Ryan

Thank you for your fast reply.
Yes. I mean voltage divider which using EN pin.

We will voltage divider(resitor divider) on EN pin for TPS7A66x-Q1.

Best Regards
Gerald
