Regarding REF pin and LDO pin outputs


Hello ST Team,


We are using L5965 power management IC in one our projects. Currently we are in design phase and like to address one concern we are facing right now. So, if anyone could clarify, then it will be boon to us.

Coming to the matter.

In the block diagram I can see a resistor is loaded with decoupling capacitors for the precision voltage reference output and LDO output in the IC. Could you please support saying the need for those resistors? and how its value is designed? What happen if we are not implementing a resistor over there?



Thanks a lot in advance!
