Hi, I want to buy LDL212PUR LDO. I have 2 questions: 1. Can it work reliably with ceramic capacitors? 2. What are the recommended resistor values for voltage adjust version?
I cannot find this information in the datasheet. Thanks, Adam
Yes, more recent LDOs such as the LDL212 are stable with ceramic caps.
According to the data sheet, the current IADJ has a typical value of 20nA. If you make the cross current through the voltage divider at least 10...20 times as large, i.e. at least 200...400nA, you can use this to calculate the (maximum) resistance values. You start with the resistance at GND (R2 in the data sheet) at which 1.18V drops and then calculate the upper resistance.
Does this answer your questions?
Good luck! /Peter
