Hello Team,Thanks for your suggestions..we will think of redesign.We wanted to understand the what are the risk may foresee, if input voltage is 30V for out put current 20mA to 100mA?and at what condition we can give 30V input?And what is Vin 7V t...

Dear Mr.Bryan Speed, Just now we have tested across the 7805 input pin, there is no AC voltage observed at DVM,and changed the input capacitor value to 10uF and out put capacitor also added 10uF(220uF cap also no difference) and check the output of t...

We are using L7805CV , Input voltage = 30V output expected = 5V with 100mA of current requirement But we are getting 7.5V, the L7805 which is not correct,may know the reason?

We are using L7805CV , Input voltage = 33V output expected = 5V with 20mA of current requirement But we are getting 7.5V, the L7805 may know the reason? according to datasheet input voltage is 35V
