LN9310 - Tiny Package Low Dropout Current Source
The LN9310 low-dropout bias supply for white LEDs is a high-performance alternative to the simple ballast resistors used in conventional white LED designs.
The LN9310 uses a internal resistor to set the bias current for six LEDs, which are matched to 3%.
