Hi team,

My customer would like to know how to delay the output voltage.

could he add the capacitor at EN pin to control the output voltage show up time?

He want to use this device, and delay 2ms.

Hello,

Yes, you can add an RC delay element between the IN and EN pins to get the desired output delay. For the fixed output version of this device, the NR pin is available to create an RC filter to reduce the device noise. There is an internal 27KΩ resistor and increasing the value of the cap connected between the NR pin and GND, should also increase the startup time. The NR pin is not available for the adjustable output voltage version of the device. Thanks!

Regards,

Srikanth
