Notes) y This application circuit is an example. The operation of mass production set is not guaranteed. Perform enough evaluation and verification on
the design of mass production set.
y Use external resistor with ±1% accuracy at CS pin.
y Use ceramic type capacitor (Typ. 1 μF, Min. 0.5 μF) at VREG pin.
y Use schottky diode at VOUT.
y This block diagram is for explaining functions. The part of the block diagram may be omitted, or it may be simplified.
