Check L7805CV information, the output should be 4.8 V to 5.2 V, I input is 8 V, after L7805CV output is 6 V, chip is broken, please? Not bad how to change circuit, makes the output 5 v?

reference 1st floor weixin_44780705 response:

add some dummy load try output side

CodePudding user response:

8 v voltage regulating input (for example: 7 ~ 9 v), to see if the output (6 v) changes?

CodePudding user response:

Normal is 4.9 v output, high is bad, or to have two feet and resistance, normal is 0 ohm!
