Hello~everybody
Recently I am using LT3507AEFE#PBF which from Linear and I met some troubles.
At the beginning,the voltage is 3.5V higher than 3.3V that the chip should output. After several tries,it has one time that even running 7V. As a result,it bacame to be same as the input voltage. The input is 25V while the current is less that 6mA. The trouble occurred in several boards. Does the chip break?
You can also see more details from the datasheet of LT3507AEFE#PBF .
Can you understand what I mean?How to solve it? Please give me some advice!
Thanks a lot !
PS: Please forgive me if there are any grammar wrong!
