Hi all,
i have a problem during bench test. i am using current source as a load to my LDO. if i set my current source to about -50mA and turn on my supply for the circuit my meter will read an almost -0.7V which i thinks is the voltage of my forwarded ESD diode. however, if my SUpply is currently ON and i load a -50mA at my output, my meter reads a 3.3V which is my the ideal output of my regulator. what is the difference between loading a -50mA then turning the supply ON and loading a -50mA when supply is already ON?
thanks
