FOperation notes

(1) Place I / O external capacitors as near as possible

to the connection pins. In particular, make sure to mini-

mize the impedance between the input-side capacitor

(C1) and pin 9.

(Reference valve: A length less than 50mm is recom-

mended for a copper foil of 1.0mm wide and 35µm thick.)

(2) Avoid frequent switching using the ON / OFF CTL

pin (5 times per second at the maximum).

(3) R1 and R2 resistors, which are used for changing

the output voltage, are usually not required.
