LMZ35003: Slow start

Shuji Ishiwata

Part Number: LMZ35003

Hi All,

I have a question about slow start.
It is stated that the SS pin must be open at 5V or less, but is it possible to set the SS time to 17msec by connecting a 22nF capacitor when the output voltage is 5V?

Best Regards,

Hi Ishiwata-san,

Datasheet recommends that it is ok to have SS be floating for output voltage @ 5V or less due to internal capacitor already being sufficient. If you want to increase SS time, adding a capacitor at the SS pin is ok.

Regards,

Richard
