Dear All, I've a problem with my step-down regulator L7985A. On power up, the DC / DC is activated when the ENABLE pin reaches about 880mV, while on the datashhet it is reported 1.2V as the ON threshold.

Dear All,

I've a problem with my step-down regulator L7985A.

On power up, the DC / DC is activated when the ENABLE pin reaches about 880mV, while on the datashhet it is reported 1.2V as the ON threshold.

Can you explain to me what this difference is due to?

I attach a figure in which are shown:

Yellow probe = Input voltage

Green probe = Output voltage

Pink probe = ENABLE voltage

Thanks in advance for your reply

Best Regards

Stefano Scremin
