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

Allowable Output Current
(vs. VIN-VOUT Voltage Difference)
VIN-IO max
The inner frame stage, on which the PTr is mounted,
is directly connected to the VOUT pin.
Therefore, enlarging the copper laminate area
around the VOUT pin is really effective for a heat
radiation.
