LM1084 input voltage
Posted: Sun Nov 26, 2017 6:34 pm
I have a chip that says LM1084. Not sure which version it is. I know there are 3.3, 5, 12, and adjustable voltage.
Specs say the input max voltage is 29 volts.
I am using a 25.2 volt AC transformer. Passing the secondary through a bridge rectifier and then a large capacitor ( 63 volts, 470uF electrolytic metal can ) I get 37 volts DC. I guess it is buffering the peak voltage. I put an LED circuit on it to drop the voltage, but it only dropped it down to 35.6 volts.
Is this unsafe for the LM1084.
