TPS7B4253-Q1: 8-pin package: time between enable is tirggered and regulation starts

Part Number: TPS7B4253-Q1

Hi,

I use the TPS7B4253-Q1 in 8-pin package.

I want to know how long is the time between Vin >2V triggers the enable logic and the adjust-pin starts to use Vref. Is there a min hold time, too?

Thanks

Hi,

For a fast Vin ramp, it typically takes around 500us. As this is analog, there is no minimum hold time and the response time will be governed by the loop response time.
