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
