KA278RXXC-Series  
2A Output Low Dropout Voltage Regulators  
Features  
Description  
The KA278RXXC is a low-dropout voltage regulator suit-  
able for various electronic equipments. It provides  
KA278RXXC-series (33/05/51/09/12)  
• 2A/3.3V, 5V, 5.1V, 9V, 12V output low dropout voltage  
regulator  
• TO-220 full-mold package (4pin)  
• Overcurrent protection, thermal shutdown  
• Overvoltage protection, short circuit protection  
• With output disable function  
constant voltage power source with TO-220-4 lead full mold  
package. The dropout voltage of KA278RXXC is below  
0.5V in full rated current(2A). This regulator has various  
functions such as a peak current protection, a thermal shut  
down, an overvoltage protection .
