NJU7223  
500mA Low Dropout Voltage Regulator  
I GENERAL DESCRIPTION  
I PACKAGE OUTLINE  
The NJU7223 series is a high precision output voltage,  
low drop output, low current consumption and high output  
current 3-terminal positive voltage regulator with a over  
current protection and a thermal shutdown.  
2
Low dropout voltage is realized at high current output.
