What voltage to use if voltage of OUTPUT pin is higher than the INPUT pin?
Latest Updated:09/01/2006
Question:
What withstanding voltage of a reverse current protection diode (which passes current flowing from the OUTPUT to INPUT) should I use when the voltage of the OUTPUT pin of my 3-terminal regulator (for a positive power supply) becomes higher than the INPUT pin's voltage?
Answer:
The withstanding voltage of the diode in this case must be higher (at least 1.2 to 1.3 times higher) than the absolute maximum rating of the 3-terminal regulator IC's input voltage.
