UC5440-0cA-UTOP203R7-UC5450-0cA pdf资料下载The UC54xx-series products are linear constant current regulators. With simple features, the UC54xx are economical devices designed to provide a cost-effective solution for current regulation of LED applications. The UC54XX lets LEDs work under stable current and avoid brightness unstable caused by current change, while their low voltage reduces power consumption. With function of negative temperature coefficient, UC54XX can protect LEDs from thermal runaway at extreme current. UC54XX also provides a wide constant current range from 5mA to 500mA. Packages of SOT23-3, SOT89-3, SOT-223, and TO252 are available.
