CO : Output capacitor (22
µF or larger)
CIN : Input capacitor (0.1 to 10
µF)
This capacitor is required in the case of an inductive
input line or long wiring.
Tantalum capacitors are recommended for C1 and C0,
particularly at low temperatures.
* Leave pin 2 open.

The inner frame stage, on which the PTr is mounted, is directly connected to the VOUT pin.
Therefore, enlarging the copper laminate area achieves a heat radiation effect of the VOUT pin.
