NJRC NJU7223DL1-30 500ma low dropout voltage regulator Datasheet

NJU7223
500mA Low Dropout Voltage Regulator
■ GENERAL DESCRIPTION
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.
