TPS7B7701-Q1: After the EN pin is pulled high, how long does it take for the voltages of Vout and Sense1 to stabilize?

Alan Xia

Part Number: TPS7B7701-Q1

Hi team.

A customer has a question about TPS7B7701 and wants to confirm.
The input voltage of TPS7B7701 is 12V, the output voltage is 5V, and the current is about 30mA. When the EN pin is pulled high, how long does it take for the voltages of Vout and Sense1 to stabilize? Does BU have relevant test data?

Hi Alan,

We are reviewing your question but before we can reply, can you please identify the customer you are supporting so we can confirm they are not on the US entity list?

Thanks,

Stephen

Thanks Alan.

Take a look at figures 16 and 17 in the datasheet - they show the startup behavior which will be the same typical behavior you would expect for 12V input and 5V output at 30 mA load. The output voltage just follows the reference voltage ramp, and there is a small delay between enabling the device and the output beginning to turn on.

Thanks,

Stephen
