What kind of diode should I use for D1 in SC of the 3-terminal regulator?

Latest Updated:09/01/2006

Question:

What kind of diode should I use for D1 in the Standard Circuit of the 3-terminal regulator's Connection section (assuming a connection whereby the OUTPUT pin has a higher voltage than the INPUT pin)?

Answer:

With the aim of mitigating damage to the power supply IC, we would recommend using a Schottky barrier diode. Note that the withstanding voltage of the diode must be equal to or higher than the voltage differential between INPUT and OUTPUT.
