RT9301

RT9301 3-Channel Low Dropout RGB LED Driver General Description The RT9301 is a 3-Channel current source driver for RGB LED. It is easy to be designed in applications that need mixing RGB light source for multi-color output. The RT9301 also provide users with great flexibility and device performance. It uses a external resistor to set the www.DataSheet4U.com bias current for three LEDs, which are matched to 3%. Users can adjust the output current from 2mA to 50mA by setting the ISET resistor. The RT9301 features very low dropout and under voltage lockout protection. It is available in a space-saving TSOT23-8 package.
