z Electrical characteristics curves
(1) Place I / O external capacitors as near as possible to the connection pins. In particular make sure to minimize the
impedance between the input-side capacitor (C1) and pin9. A length less than 50mm is recommended for a copper
foil of 1.0mm wide 35µm trick.
(2) Avoid frequent switching using the ON / OFF CTL pin (five times per second at the maximum).
(3) R1 and R2 resistors, which are used for changing the output voltage, are usually not required.
