i have an emergency light circuit that uses power from telephone line. input voltage is 52 volt and it comes to a 4 diode bridge rectifier. positive output of this rectifier goes to LM 317 IC's input. My friend told me that never connect a voltage bigger than 35 to LM 317 IC's input. so i need to know what is the output voltage of bride rectifier in this circuit.
