●Low dissipation current

(Dissipation current at no load: MAX. 2mA Output OFF-state dissipation current: MAX.5µA)

●Low power-loss

●Built-in overcurrent and overheat protection functions

●TO-263 package

■ Applications

●Peripheral equipment of personal computers

●Power supplies for various electronic equipment such as DVD player or STB
