following expression:  
Output ripple noise is measured after connection of the indicated  
external capacitor Co to the output terminals.  
External voltage<R2×1mA+2.5(Unit: V)  
[EXTERNAL RESISTANCE METHOD]: Refer to OUTPUT  
VOLTAGE VARIABLE CHARACTERISTICS  
An external resistance RA is placed between terminal No.  
5(Vout) and No.6(Vset). This controls the output voltage(Vout).  
Voltage changes per the following equation.  
Vout=0.5769×[68×RA/(69.3+RA)]+0.75

PRECAUTIONS  
• Install the components according to CIRCUIT DIAGRAM.  
• This product operates only after the input-capacitor is  
connected.  
PACKAGING STYLE AND QUANTITY  
• Tray(1 layer: 50 pieces, 1 carton: 450 pieces max.)  
• Taping(500 pieces)  
• Parallel operation to increase output current is not possible.  
• Input fuse  
A fuse should be connected to the input with a current rating 3  
times that of the rated(normal) input current.  
All specifications are subject to change without notice.
