Typical application circuit example

• An input electrolytic capacitor, CIN , of approximately 220 μF should be connected to the input

side of the BR300. If the input voltage is stable, it is not required.

• An output capacitor, CO, either electrolytic of approximately 470 μF or ceramic of

approximately 30 μF should be connected to the output side of the BR300.

• For CIN , a YXF type made by Rubycon for switching power supplies or equivalent is

recommended.

• For CO , either a low impedance ZL type made by Rubycon, or three ceramic capacitors

connected in parallel (GRM31CR71E106KA12 made by Murata), for switching power

supplies or equivalent are recommended.

• Depending on PCB layout, output voltage ripple could be amplified. Please check the output

voltage ripple in the actual application.
