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.
Low dropout voltage is realized at high current output.
