The RT9301 is a 3-Channel current source driver for RGBLED. It is easy to be designed in applications that needmixing RGB light source for multi-color output.The RT9301 also provide users with great flexibility anddevice performance. It uses a external resistor to set thebias current for three LEDs, which are matched to 3%.Users can adjust the output current from 2mA to 50mA bysetting the ISET resistor.The RT9301 features very low dropout and under voltagelockout protection. It is available in a space-saving TSOT-23-8 package.
