I am using MIC29302UW IC for converting 12V to 3.8V. I am using this IC from last 2 years and have used this LDO in more than 50 devices. But the same IC is not working in my new PCB board. I even made a small PCB, only for testing the working of MIC29302UW,but its not showing the correct output.
Let me explain the issue- I am providing 12V at the input of MIC29302UW and using 100k(R1) and 47.7(R2) resistors to form feedback loop. But instead of getting 3.8V(approx.), its showing 12V at the output pin. The input voltage is not stepping down from 12V to 3.8V.
So, what i can do to rectify this error and make it working? I have bought this LDO IC from DIGI-KEY. So, i am hoping that there is no fault in the IC.
NOTE: I am using the original MIC29302UW from DIGI-KEY.
